Usage

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.')
