Text input augmented with Lexer magic✨ to support advanced search features. Searchbox supports multiple user-defined keywords (filters, variables) and also NOT operator.

Features

• [x] Parses user input string into a structured formula of literals.
• [x] Supports literal negation.
• [x] Supports unicode.
• [ ] Operators are configurable.

Usage

import * as searchbox from '@webkitty/searchbox';

const inputText = 'Never take title:raisins from -author:rabbits';
const keywords = ['title', 'author'];

const formula = searchbox.parse(inputText, {keywords});

// Formula:
//  _: [Never,take,from]	// words not matching any keyword (aka fulltext)
//  title: [raisins]		// "title" keyword match
//  -author: [rabbits]		// "author" keyword match with NOT operator ("-")

Please note that only case-sensitive keyword matching is supported.
