This tiny project provides ability to convert a boolean query string to regular expressions.
npm install --save lucene-to-regex
const ltr = require('lucene-to-regex') const regex = ltr.toRegex('Lucene AND Regex AND (easy NOT difficult)', 'i') // regex: /^(?=.*?\bLucene\b)(?=.*?\bRegex\b)(?=.*?(?=.*?\beasy\b)(?!.*?\bdifficult\b)).*$/i regex.test('Regex and Lucene are easy.') // result: true regex.test('Lucene and regex are difficult.') // result: false
You can set flag by passing an additional parameter to the method.
