Thanks a lot! It's nice to hear that from a Google developer. :) We
hope it's enough to bridge the gap until Google releases super-
powerful full-text search support (with ranking and spellchecking and
phonetic matching and ...).

Some low-level parts *should* work directly with any framework (as we
just derive from db.StringListProperty). We haven't tested it, but I'm
pretty sure if you rip out the values index the Base package would run
with webapp, too, though a few app-engine-patch/ragendja utility
functions might still be needed.
The values index (or "DISTINCT" index) requires special app-engine-
patch extensions because it has to be compatible with transactions. If
you modify an entity within a transaction gae-search has to wait for
the transaction to finish and only then it's possible to update the
values index (which would be in different entity groups). Also, we
have to know whether the transaction finished successfully before we
can actually update the values index. Here, app-engine-patch provides
a few extra signals (post_save_committed, post_delete_committed) which
we handle in order to update the index. We plan to port the updater to
the new background processing API and maybe that can obviate the need
for those signals. So, a future release of the Base package might even
support webapp (if there is enough interest).
The higher-level parts in the Premium package (e.g., the views and
templates) require more complete Django support (more than what django-
helper can provide). Though, we already removed the dependency on
generic views, so it might be possible to support django-helper in a
future release, too.
Finally, the "auto-complete" jQuery plugin is independent of any
framework, of course.
