What were you thinking of for indexing? Just catalog stuff? More general?
I was considering just using zope.index but I haven't really thought much about
There's been a tension in the opencore stuff with the catalog, mostly
that it's easy to setup and use for things, but it doesn't really work
for things outside of the ZODB. Or, I guess theoretically you could
catalog things not in the ZODB, but it's never happened.
IMO, mostly it's a matter of deciding what "index" and "catalog" means for
searching. If you only need full-text search, some indexing systems are totally
inappropriate. Likewise, if you only need "field" indexes that match just one
particular value, it's sometimes vastly simpler just to come up with your own
system based on, e.g. a relational table, than it is to try to use somebody
else's "indexer" or "catalog".
That said, there's a real need for cross-system indexing of different
kinds. There's text search indexes, but other kinds of more strict
indexes also make sense. It would be very handy to have an index that
wasn't tied to the ZODB, a database, or anything else. (It could be
implemented using the ZODB or a database, of course.)
Xapian seems like a good choice too. It has its own persistence mechanism and
reasonable Python bindings (although from experience maybe slightly memory-leaky).
