Apache Lucene is an open source popular library for Information Retrieval tasks. The library is implemented in Java and has ports or API bindings in multiple languages such as Python, Ruby, C#, etc. If you need full text search functionality in your application you can add it with Lucene. Text search is the most common application of the library but not the only one. For example, you can compute text similarity with Lucene using different measures provided with the library or add custom similarity algorithms.
