The Xapian API doesn't provide any functionality to recurse or iterate
directories, or open files and load their contents (such APIs already
exist, so why reinvent the wheel?)  But once you've read a file, you can
pass its contents to Xapian to index and then later search the database
to find matching files.

Or just use the omindex program from Omega to do the indexing, and your
own Java code to search.

The C++ API documentation is the best reference, except that method
names are mapped to match Java conventions (to get_mset -> getMSet).
The Java wrappers are lagging a bit currently, because they're
hand-coded JNI which is painful to update.  I've been slowly working
on some new wrappers based on SWIG, but haven't had time to work
on them for a while I'm afraid.

There are some Java examples in the source code - you can find them
online here:
