I haven't looked at your code, but it sounds like you've taken
slightly the wrong approach.

The intended way to do this is that you'd implement an RBSourceSearch
subclass that converts search text into rhythmdb queries (sounds like
you've already got this code), then attach that to the search bar as
follows:

- create a GtkAction for your search type; the label for this action
will appear in the search bar
- associate your search object with the action;
search.action_attach(action), more or less
- attach a handler to the RBSourceHeader get-search-actions signal -
you can get at this object via the shell's source-header property. The
handler would return an array containing the name of your GtkAction
- trigger the refresh-search-bar signal on the source header to ensure
it picks up your new search action

I used to have a simple example plugin that added a 'location' search
type, but I seem to have lost it somewhere along the line.

This will work for any source that uses the search bar, and it filters
through the library browser correctly too.
