search-text-tokenizer

A search query tokeniser inspired by Google.

• Split a space-delimitered query string into an array of terms
• Treat quoted terms as phrases
• Support tagged terms (tag:term)
• Detect excluded terms (-term)

Examples

var tokenizer = require( 'search-text-tokenizer' );

console.log( tokenizer( 'red bull' ) );
// [ { term: 'red' }, { term: 'bull' } ]

var result = console.log( tokenizer( '"red bull" "gives you wings"' ) );
// [ { term: 'red bull', phrase: true }, { term: 'gives you wings', phrase: true } ]

result = console.log( tokenizer( 'author:tolkien' ) );
// [ { term: 'tolkien', tag: 'author' } ]

result = console.log( tokenizer( '-car' ) );
// [ { term: 'car', exclude: true } ]
