[Zope3-dev] Catalog is back

[Jim Fulton]

Yesterday, I finished recovering the catalog code, making it work
with the new event system and unique id utility.  (Note that
Albertas Agejevas and Gintautas Miliauskas of POV did much of the
work at the EuroPython sprint).

The hard part, getting the events hooked up, is done.

It works but could use lots of improvements.  In particular, the
indexing APIs don't faciliate merging search results the way they
should or ranking. (There is a ISimpleQuery interface that has to
go. :)  Someone with experience with Zope 2 catalogs could easily
make substantial improvements.

The catalog and indexes havd minimal UIs. Nicer UIs would be great.

Finally note that there is a fairly detailed explanation
(and functional test) of how to set up and use catalogs in
src/zope/app/catalog/README.txt.
