You ignore SearchTermResponse in most of the cases. You might want to
look at the example code
http://svn.gnome.org/viewvc/beagle/trunk/libbeagle/wrappers/python/examples/
or the code for deskbar and yaBi.

You are doing nothing wrong. Querying is really an async process. You
get the SearchTermResponse initially (which most apps wont need and
can be ignored) and wait till you hear HitsAddedResponse or
FInishedResponse. If you want to make it look like sync, use some kind
of mutex to block the process till you receive FinishedResponse.

Since you mention webapp, just make sure the webapp allows you to run
a glib mainloop. I have faced this problem before - some execution
environments do not allow any other mainloop. Beagle requires a glib
mainloop.
