Firebird Gets the Eye of the Sphinx- full-text search engine
Sphinx is a very powerful and popular free open source full-text search engine. A few days ago, Sphinx 0.9.8.1 was released. Vlad Khorsun and Pierre Yager made a patch for Sphinx to support Firebird. Their patches and Windows binary are available to download and try out.
It’s an great search engine used a lot in the LAMP world So now for example if you create and phpbb site with firebird back end , you can use sphinx for indexing and fast search. Another idea is : use it to index the whole database if you have large quantities of text and you need to search for keywords (an movie comments database for example)
