search instantsearch client

Meilisearch is an open-source search engine. Discover what Meilisearch is!

This library is the search client that you should use to make Meilisearch work with InstantSearch. InstantSearch, an open-source project developed by Algolia, is the tool that renders all the components needed to start searching in your front-end application.

Instead of reinventing the wheel, we have opted to reuse the InstantSearch library for our own front-end tooling. We will contribute upstream any improvements that may result from our adoption of InstantSearch.

If you use Angular, React, or Vue, you might want to check out these repositories:

NB: If you don't have any Meilisearch instance running and containing your data, you should take a look at this getting started page.

📖 Documentation

For general information on how to use Meilisearch—such as our API reference, tutorials, guides, and in-depth articles—refer to our main documentation website.

⚡ Supercharge your Meilisearch experience

Say goodbye to server deployment and manual updates with Meilisearch Cloud. No credit card required.

🔧 Installation

Use npm or yarn to install instant-meilisearch:

npm install @meilisearch/instant-meilisearch

yarn add @meilisearch/instant-meilisearch

instant-meilisearch is a client for instantsearch.js. It does not create any UI component by itself. To be able to create a search interface, you'll need to install instantsearch.js as well.

🎬 Usage

Basic

import { instantMeiliSearch } from '@meilisearch/instant-meilisearch'

const { searchClient, setMeiliSearchParams } = instantMeiliSearch(
  'https://ms-adf78ae33284-106.lon.meilisearch.io', // Host
  'a63da4928426f12639e19d62886f621130f3fa9ff3c7534c5d179f0f51c4f303' // API key
)

where searchClient is to be passed to instantsearch.js or its many framework adaptations, and setMeiliSearchParams is a function used to set/modify certain Meilisearch search parameters to be overridden.

Parameters

Host - URL of Meilisearch instance
API Key - Meilisearch access API Key. This can either be a string or a synchronous function that returns a string. ⚠️ Prefer using a key with only search permissions as it is used on your front-end.

💅 Customization

instant-meilisearch offers some options you can set to further fit your needs.

placeholderSearch: Enable or disable placeholder search (default: true).
finitePagination: Enable finite pagination when using the pagination widget (default: false) .
primaryKey: Specify the primary key of your documents (default undefined).
keepZeroFacets: Show the facets value even when they have 0 matches (default false).
requestConfig: Use custom request configurations.
httpClient: Use a custom HTTP client.
meiliSearchParams: Override a selection of Meilisearch search parameters (default undefined).

The options are added as the third parameter of the instantMeilisearch function.

import { instantMeiliSearch } from '@meilisearch/instant-meilisearch'

const { searchClient } = instantMeiliSearch(
  'https://ms-adf78ae33284-106.lon.meilisearch.io',
  'a63da4928426f12639e19d62886f621130f3fa9ff3c7534c5d179f0f51c4f303',
  {
    placeholderSearch: false, // default: true.
    primaryKey: 'id', // default: undefined
    // ...
  }
)

Placeholder Search

Placeholders search means showing results even when the search query is empty. By default it is true. When placeholder search is set to false, no results appears when searching on no characters. For example, if the query is "" no results appear.

{ placeholderSearch : true } // default true

Finite Pagination

Finite pagination is used when you want to add a numbered pagination at the bottom of your hits (for example: << < 1, 2, 3 > >>).

It requires the usage of the Pagination widget.

Example:

{ finitePagination: true } // default: false

Primary key

Specify the field in your documents containing the unique identifier (undefined by default). By adding this option, we avoid instantSearch errors that are thrown in the browser console. In React particularly, this option removes the Each child in a list should have a unique "key" prop error.

{ primaryKey : 'id' } // default: undefined

Keep zero facets

keepZeroFacets set to true keeps the facets even when they have 0 matching documents (default false).

When using refinementList it happens that by checking some facets, the ones with no more valid documents disapear. Nonetheless you might want to still showcase them even if they have 0 matched documents with the current request:

Without keepZeroFacets set to true: genres:

[x] horror (2000)
[x] thriller (214)
[ ] comedy (0)

With keepZeroFacets set to false, comedy disapears:

genres:

[x] horror (2000)
[x] thriller (214)

{ keepZeroFacets : true } // default: false

Request Config

You can provide a custom request configuration. Available field can be found here.

for example, with custom headers.

{
  requestConfig: {
    headers: {
      Authorization: AUTH_TOKEN
    },
    credentials: 'include'
  }
}

Custom HTTP client

You can use your own HTTP client, for example, with axios.

{
  httpClient: async (url, opts) => {
    const response = await $axios.request({
      url,
      data: opts?.body,
      headers: opts?.headers,
      method: (opts?.method?.toLocaleUpperCase() as Method) ?? 'GET'
    })
    return response.data
  }
}

Meilisearch search parameters

meiliSearchParams lets you override a set of search parameters that are sent off to Meilisearch. The following options can be overridden:

instantMeiliSearch(
  // ...
  {
    meiliSearchParams: {
      attributesToHighlight: ['overview'],
      highlightPreTag: '<em>',
      highlightPostTag: '</em>',
      attributesToSearchOn: ['overview'],
    },
  }
)

Modify Meilisearch search parameters

instantMeiliSearch returns an instance with two properties on it, one of them being setMeiliSearchParams.

const { searchClient, setMeiliSearchParams } = instantMeiliSearch(/*...*/)

It modifies (or sets if not already set) the overridden Meilisearch search parameters. It only modifies parameters that are defined on the provided object, the following will not change attributesToHighlight.

const { setMeiliSearchParams } = instantMeiliSearch(
  // ...
  {
    meiliSearchParams: {
      attributesToHighlight: ['overview'],
      highlightPreTag: '<em>',
      highlightPostTag: '</em>',
      attributesToSearchOn: ['overview'],
    },
  }
)

setMeiliSearchParams({
  highlightPreTag: '<mark>',
  highlightPostTag: '</mark>',
  attributesToSearchOn: ['overview', 'title'],
})

🪡 Example with InstantSearch

The open-source InstantSearch library powered by Algolia provides all the front-end tools you need to highly customize your search bar environment.

InstantSearch requires that you provide an indexName. The indexName corresponds to the index uid in which your document are stored in Meilisearch.

In index.html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
  </head>

  <body>
    <div>
      <div id="searchbox"></div>
      <div id="hits"></div>
    </div>

    <script src="https://cdn.jsdelivr.net/npm/@meilisearch/instant-meilisearch/dist/instant-meilisearch.umd.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/instantsearch.js@4"></script>
    <script src="./app.js"></script>
  </body>
</html>

In app.js:

const { searchClient } = instantMeiliSearch(
  'https://ms-adf78ae33284-106.lon.meilisearch.io',
  'a63da4928426f12639e19d62886f621130f3fa9ff3c7534c5d179f0f51c4f303'
)

const search = instantsearch({
  indexName: 'steam-video-games',
  searchClient,
})

search.addWidgets([
  instantsearch.widgets.searchBox({
    container: '#searchbox',
  }),
  instantsearch.widgets.hits({
    container: '#hits',
    templates: {
      item: `
        <div>
          <div class="hit-name">
            {{#helpers.highlight}}{ "attribute": "name" }{{/helpers.highlight}}
          </div>
        </div>
      `,
    },
  }),
])

search.start()

📜 API resources

List of all the components that are available in instantSearch and their compatibility with Meilisearch.

Table Of Widgets

✅ InstantSearch

instantSearch references

instantSearch is the main component. It manages the widget and lets you add new ones.

✅ IndexName: uid of your index. required
✅ SearchClient: Search client, in our case instant-meilisearch. See customization for details on options. required
❌ numberLocale: Does not work with both Algoliasearch and instant-meilisearch.
✅ searchFunction: Surcharge the search function provided by the search client.
✅ initialUiState: Determine the search state on app start.
✅ onStateChange: Change search state on change (see option above).
✅ stalledSearchDelay: Time in ms before search is considered stalled. Used for loader.

const search = instantsearch({
  indexName: 'instant_search',
  searchClient: instantMeiliSearch(
    'https://ms-adf78ae33284-106.lon.meilisearch.io',
    'a63da4928426f12639e19d62886f621130f3fa9ff3c7534c5d179f0f51c4f303',
    {
      // ... InstantMeiliSearch options
    }
  ).searchClient,
  // ... InstantSearch options
  routing: true // for example
})

✅ Index

Index references

Index is the component that lets you apply widgets to a dedicated index. It’s useful if you want to build an interface that targets multiple indices.

✅ SearchBox

SearchBox references

The searchBox widget is used to let the user perform a text-based query.

✅ container: The CSS Selector or HTMLElement to insert the widget into. required
✅ placeholder: Placeholder of the search box.
✅ autofocus: Whether the search box is focused on arrival.
✅ searchAsYouType: Whether result appears as you type or after pressing enter.
❌ showReset: Does not work with both algoliasearch and instant-meilisearch

✅ Configure

Configure references: See #389

The configure widget lets you provide raw search parameters to the Algolia API without rendering anything.

Because these are the search parameters of AlgoliaSearch and not the InstantSearch parameters, some of them are ignored by InstantSearch. Since we do not act as AlgoliaSearch on search parameters, detailed compatibility can be found in this issue. This component should only be used if no other component provides the same configuration.

We also suggest looking at Meilisearch's search parameters to determine how they act.

instantsearch.widgets.configure({
  hitsPerPage: 20,
  // other algoliasearch parameters
})

❌ ConfigureRelatedItems

ConfigureRelatedItems references.

No compatibility with Meilisearch because the component uses sumOrFiltersScores and optionalFilters search parameters that do not exist in Meilisearch.

Panel

The panel widget wraps other widgets in a consistent panel design.

✅ hidden: Function to determine if pannel should be hidden on earch render.
✅ collapsed: Function to determine if pannel should be collapsed on earch render.
✅ templates: The templates to use for the widget.
✅ cssClasses: The CSS classes to override.

Provides all the data and functions from the widgets.

It works only on widgets that are compatible with instant-meilisearch.

✅ Hits

hits references

Used to display a list of results.

✅ container: The CSS Selector or HTMLElement to insert the hits into. required
✅ escapeHTML: Escapes HTML tags in string values in returned hits.
✅ transformItems: Function that maps over every hit the provided logic.
✅ templates: The templates to use for the widget.
✅ cssClasses: The CSS classes to override.

instantsearch.widgets.hits({
  container: '#hits',
  templates: {
    item: `
        <div>
          <div class="hit-name">
            {{#helpers.highlight}}{ "attribute": "title" }{{/helpers.highlight}}
          </div>
        </div>
      `,
  },
})

✅ InfiniteHits

infiniteHits references

The infiniteHits widget is used to display a list of results with a “Show more” button.

✅ container: The CSS Selector or HTMLElement to insert the hits into. required
✅ escapeHTML: Escapes HTML tags in string values in returned hits.
✅ transformItems: Function that maps over every hit the provided logic.
✅ templates: The templates to use for the widget.
✅ cssClasses: The CSS classes to override.
❌ showPrevious: Does not work with both Algoliasearch and InstantMeilisearch.
❌ cache: Not added in InstantMeilisearch.

instantsearch.widgets.infiniteHits({
  container: '#infinite-hits',
  templates: {
    item: `
      <h2>
        {{#helpers.highlight}}{ "attribute": "name" }{{/helpers.highlight}}
      </h2>
    `,
  },
})

✅ Highlight

highlight references

The highlight function returns an attribute from a hit into its highlighted form, when relevant.

✅ attribute: The attribute of the record to highlight. required
✅ hit: Hit object. required
✅ highlightedTagName: HTML element to wrap the highlighted parts of the string.

See Hits for an example.

✅ Snippet

Snippet references

The snippet function returns an attribute from a hit into its snippet form, when relevant.

✅ attribute: The attribute of the record to snippet and highlight. required
✅ hit: Hit object. required
✅ highlightedTagName: HTML element to wrap the highlighted parts of the string.

Note that the attribute has to be added to attributesToSnippet in configuration. Highlight is applied on snippeted fields.

Snippeting is called cropping in Meilisearch, more about it here. It is possible to change the size of the snippeting by adding its character size in the attributesToSnippet parameter. For example: "description:40".

The 40 value represents the number of characters (rounded down to always have full words) and not the number of words. Thus, the snippet string size is always equal to or lower than 40 characters.

instantsearch.widgets.configure({
  attributesToSnippet: ['description:40'],
})

instantsearch.widgets.hits({
  // ...
  templates: {
    item: `
      <p>{{#helpers.snippet}}{ "attribute": "description" }{{/helpers.snippet}}</p>
    `,
  },
})

✅ Geo Search

Geo search references

The geoSearch widget displays search results on a Google Map. It lets you search for results based on their position and provides some common usage patterns such as “search on map interactions”.

✅ container: The CSS Selector or HTMLElement to insert the Google maps into. required
✅ googleReference: The reference to the global window.google object. See the Google Maps documentation for more information. required
✅ initialZoom: When no search results are found, google map will default to this zoom.
✅ initialPosition: When no search results are found, google map will default to this position.
✅ mapOptions: The options forwarded to the Google Maps constructor.
❔ builtInMarker: Used to customize Google Maps markers. Because of lack of tests we cannot guarantee its compatibility. For more information please visit InstantSearch related documentation.
customHTMLMarker: Same as builtInMarker. Because of lack of tests, we cannot guarantee its compatibility. For more information please visit InstantSearch related documentation.
✅ enableRefine: If true, the map is used for refining the search. Otherwise, it’s only for display purposes.
✅ enableClearMapRefinement: If true, a button is displayed on the map when the refinement is coming from interacting with it, to remove it.
✅ enableRefineControl: If true, the map is used for refining the search. Otherwise, it’s only for display purposes.
✅ enableRefineOnMapMove: If true, a button is displayed on the map when the refinement is coming from interacting with it, to remove it.,
✅ templates: The templates to use for the widget.
✅ cssClasses: The CSS classes to override.

See our playground for a working exemple and this section in our contributing guide to set up your Meilisearch.

Requirements

The Geosearch widgey only works with a valid Google API key.

In order to communicate your Google API key, your instantSearch widget should be surrounded by the following function:

import injectScript from 'scriptjs'

injectScript(
  `https://maps.googleapis.com/maps/api/js?v=quarterly&key=${GOOGLE_API}`,
  () => {
      const search = instantsearch({
      indexName: 'geo',
      // ...
      })
      // ...
  })

Replace ${GOOGLE_API} with you google api key.

See code example in the playground

Usage

The classic usage, with only the required elements, renders an embedded Google Map on which you can move and refine search based on the position maps.

  instantsearch.widgets.geoSearch({
    container: '#maps',
    googleReference: window.google,
  }),

For further customization, for example to determine an initial position for the map. Contrary to initialZoom and initialPosition, triggers a search request with the provided information.

The following parameters exist:

boundingBox: The Google Map window box. It is used as parameter in a search request. It takes precedent on all the following parameters.
aroundLatLng: The middle point of the Google Map. If insideBoundingBox or boundingBox is present, it is ignored.
aroundRadius: The radius around a Geo Point, used for sorting in the search request. It only works if aroundLatLng is present as well. If insideBoundingBox or boundingBox is present, it is ignored.

For exemple, by adding boundingBox in the instantSearch widget parameters, the parameter will be used as a search parameter for the first request.

  initialUiState: {
    geo: {
      geoSearch: {
        boundingBox:
          '50.680720183653065, 3.273798366642514,50.55969330590075, 2.9625244444490253',
      },
    },
  },

Without providing this parameter, Google Maps will default to a window containing all markers from the provided search results.

Alternatively, the parameters can be passed through the searchFunction parameter of the instantSearch widget. Contrary to initialUiState these parameters overwrite the values on each search.

  searchFunction: function (helper) {
    helper.setQueryParameter('aroundRadius', 75000)
    helper.setQueryParameter('aroundLatLng', '51.1241999, 9.662499900000057');
    helper.search()
  },

❌ QueryRuleCustomData

QueryRuleCustomData references

You may want to use this widget to display banners or recommendations returned by Rules, and that match search parameters.

No compatibility because Meilisearch does not support Rules.

❌ QueryRuleContext

Query rule context references

The queryRuleContext widget lets you apply ruleContexts based on filters to trigger context-dependent Rules.

No compatibility because Meilisearch does not support Rules.

✅ SortBy

Sort by references

The SortBy widget is used to create multiple sort formulas. Allowing a user to change the way hits are sorted.

✅ container: The CSS Selector or HTMLElement to insert the widget into. required
✅ items: The list of different sorting possibilities. required
✅ cssClasses: The CSS classes to override.
✅ transformItems: function receiving the items, called before displaying them.

The usage of the SortBy widget differs from the one found in Algolia's documentation. In instant-meilisearch the following is possible:

Sort using different indexes.
Different sort rules on the same index.

The items list is composed of objects containing every sort possibility you want to provide to your user. Each object must contain two fields:

label: What is showcased on the user interface ex: Sort by Ascending Price
value: The sort formula.

Sort formula

A sort formula is expressed like this: index:attribute:order.

index is mandatory, and when adding attribute:order, they must always be added together.

When sorting on an attribute, the attribute has to be added to the sortableAttributes setting on your index.

Example:

[
  { label: 'Sort By Price', value: 'clothes:price:asc' }
]

In this scenario, in the clothes index, we want the price to be sorted in an ascending way. For this formula to be valid, price must be added to the sortableAttributes settings of the clothes index.

Relevancy

The impact sorting has on the returned hits is determined by the ranking-rules ordered list of each index. The sort ranking-rule position in the list makes sorting documents more or less important than other rules. If you want to change the sort impact on the relevancy, it is possible to change it in the ranking-rule setting. For example, to favor exhaustivity over relevancy.

See relevancy guide.

Example

  instantsearch.widgets.sortBy({
    container: '#sort-by',
    items: [
      { value: 'clothes', label: 'Relevant' }, // default index
      {
        value: 'clothes:price:desc', // Sort on descending price
        label: 'Ascending price using query time sort',
      },
      {
        value: 'clothes:price:asc', // Sort on ascending price
        label: 'Descending price using query time sort',
      },
      {
        value: 'clothes-sorted', // different index with different ranking rules.
        label: 'Custom sort using a different index',
      },
    ],
  }),

❌ RelevantSort

Relevant Sort references

Virtual indices allow you to use Relevant sort, a sorting mechanism that favors relevancy over the attribute you’re sorting on.

✅ Routing

Routing is configured inside instantSearch component. Please refer to the documentation for further implementation information.
