<h3>World's fastest and most memory efficient full text search library with zero dependencies.</h3> <h3>World's fastest and most memory efficient full text search library with zero dependencies.</h3>
When it comes to raw search speed <a href="https://jsperf.com/compare-search-libraries" target="_blank">FlexSearch outperforms every single searching library out there</a> and also provides flexible search capabilities like multi-word matching, phonetic transformations or partial matching. It also has the __most memory-efficient index__. Keep in mind that updating existing items from the index has a significant cost. When your index needs to be updated continuously then <a href="bulksearch/" target="_blank">BulkSearch</a> may be a better choice. FlexSearch also provides you a non-blocking asynchronous processing model as well as web workers to perform any updates on the index as well as queries through dedicated threads.

The basic idea of this concept is to limit relevance by its context instead of calculating relevance through the whole (unlimited) distance. The basic idea of this concept is to limit relevance by its context instead of calculating relevance through the whole (unlimited) distance.
Imagine you add a text block of some sentences to an index ID. Assuming the query includes a combination of first and last word from this text block, are they really relevant to each other?
