I tried to get into Lucene (using SOLR) recently but was put off by it's complexity for what was, in my case, a simple use case (searching through a large document set of html, txt, and doc files quickly using proximity search).<p>After futzing for hours with XSLT and writing scripts to submit content via the REST API, I found out about FTS4 in SQLite, and was impressed by it's relative simplicity. I had something working in under an hour in Python.
