Paxle: Search Engine Framework in Java

Paxle [1] is a framework targeted at indexing and searching documents. It is based on OSGi and already contains all modules needed to operate a search engine (crawler, indexer, storage, controlling the modules, …). However, in Paxle the modules are interchangable, following the model of Lego bricks.

Paxle is written in Java, uses Apache's Lucene. Check out the features page.
