com.sun.star.help.HelpSearch and com.sun.star.help.HelpIndexer services.

I added it as the "clucene" module with a bunch of help from dtardon and

Can you add yourself to
http://wiki.documentfoundation.org/Development/Developers and link to an
email confirming that this is under LGPLv3+/MPLv1.1 and I'll see about
merging it in.
