Users of Firebird 3, 4 and 5 can use free open source IBSurgeon FTS UDR library to implement full text search procedures and functions for Firebird SQL, to run them in SQL queries, using the powerful capabilities of Lucene search engine.

UDR is based on Lucene++, the C++ implementation of Lucene search engine, to achieve the fastest search with true full text search capabilities. This UDR is 100% free and open source, with LGPL license.

Windows and Linux versions are available: for Windows we have ready-to-use binaries and for Linux it is necessary to build UDR to work on the specific distribution (we have easy building instruction).

The library is developed by the grant from IBSurgeon.
