Latest commit 1aa3ab0 Aug 26, 2015 @dbalmain Add missing bzlib function
In updating bzlib I missed adding an error function required by the newer
version: +bz_internal_error+. This broke the C build, although it had no effect
on the ruby bindings. Fixed!

Ferret is an information retrieval library in the same vein as Apache Lucene. Originally it was a full port of Lucene but it now uses it's own file format and indexing algorithm although it is still very similar in many ways to Lucene. Everything you can do in Lucene you should be able to do in Ferret.


c/ Ferret is written in C for speed. The actual C code should be fairly easy to use in an application or create bindings to a language other than Ruby.

ruby/ This directory contains the Ruby bindings and tests. See ruby/README.md for information on installing Ferret's Ruby bindings
