[Zope] request for advice: using ZCatalog

[Chris McDonough]

If I were you, I'd wait for 2.3 final.  There are some significant changes
that need to make it into 2.3 yet as far as ZCatalog goes, including some
textindex bugfixes and merging of textindexes on update.  2.2.5 has some
Catalog bugfixes, but more bugs have been discovered and squashed since
then.
