Install

npm install feathers-nedb-puzzy-search

Usage

const search = require('feathers-nedb-puzzy-search')
const messages = app.service('messages')

// enable for message service, may use app.hooks too
messages.hooks({
  before: {
    find: search({['name', 'email']})
  }
})

let res = await service.find({ query: { name: { $search: 'ello' } } })
let res = await service.find({ query: $search: 'ello' } })

Besure to whitelist non-standard query parameters in your model. That's ['$text', '$regex'] for MongoDB , and ['$where', '$regex'] for NeDB.

Options

feathers-nedb-puzzy-search take two options in NeDB $where mode:

search({
  fields: ['search.this.path', 'this.path.too', 'title'],
  deep: true
})

• fields - Specify which fields to search.
• deep- If true and fields is undefined, will search deep in objects.

In NeDB $regex mode it takes as service options the following:

• excludeFields - Specify which fields to exclude from search.
• fields - Specify which fields to search. Mutually exclusive.

As query parameters it also takes $caseSensitive

Complete example

const feathers = require('feathers')
const hooks = require('feathers-hooks')
const NeDB = require('nedb')
const service = require('feathers-nedb')
const search = require('feathers-nedb-puzzy-search')

const Model = new NeDB({
  filename: './example.db',
  autoload: true
})

const app = feathers()
app.configure(hooks())
app.use('/test', service({ Model }))
app.hooks({
  before: {
    find: search({
      // if omitted, then it will search all properties of documents
      fields: ['title', 'description']
    })
  }
})

// you need node v7 or above for async / await syntax
async function testDatabase () {
  let service = app.service('test')
  await service.create([
    { 'title': 'asdf' },
    { 'title': 'qwerty' },
    { 'title': 'zxcvb' },
    { 'title': 'hello world' },
    { 'title': 'world around' },
    { 'title': 'cats are awesome' },
  ])

  let res = await service.find({ query: { $search: 'world' } })
  let res = await service.find({ query: { title: { $search: 'ello' } } })

  console.log(res)
  // [ { title: 'world around', _id: '1RDM5BJWX4DWr1Jg' },
  //   { title: 'hello world', _id: 'dX4bpdM1IsAFkAZd' } ]
  //   { title: 'hello world', _id: 'dX4bpdM1IsAFkAZd' } ]
}

testDatabase()
  .catch(e => console.error(e))
