Lucene?
by Michael Schuerig on Wednesday 23/Feb/2005, @06:42

Has anyone of you had a look at the Java search framework Lucene (http://lucene.apache.org/java/docs/index.html) and its C++ port, CLucene (http://sourceforge.net/projects/clucene/), in particular?

Lucene is an excellent, sophisticated and yet easily usable framework for indexing and searching. It might be usable as is or for inspiration only.

Definitely agreed. Also note that Beagle uses a C# port of Lucene. Lucene's index format is well documented, and there are also ports to languages like Python (http://pylucene.osafoundation.org). It supports a
flexible query syntax, and support for many natural languages. I think the best choice KDE could do is choose Lucene as index format.

Lucene is a fine tool -- and CLucene as well and something that I've looked at, but part of what I was trying to indicate in the interview is that we're not working on a "search tool" -- search is just one of the things that we'll be using it for. Lucene is well set up for static document indexing, but isn't particularly useful for a graph based contextual web.

This is kind of a problem right now that we didn't have when these ideas were hatched -- people have ideas in mind for what "desktop search" is and that's not really what we're working on. The questions even kind of indicated that -- if I'd done an interview on this stuff last June or so the questions would have been very different because that was before all of this stuff kind of burst onto the main stream.

KDE already has a plugin based metadata layer, extending that to where it can extract the needed information is likely the direction that things will move.
