World's fastest and most memory efficient full text search library with zero dependencies.

+ When it comes to raw search speed FlexSearch outperforms every single searching library out there and also provides flexible search capabilities like multi-word matching, phonetic transformations or partial matching. -It also has the most memory-efficient index. - +It also has the most memory-efficient index. FlexSearch also provides you a non-blocking asynchronous processing model as well as web workers to perform any updates or queries on the index in parallel through dedicated balanced threads.
