Ok, so it seems its not - my objects are not so much text-based.

Thats exactly my question - if there is some advice out there how to do that.
I'm very well aware that I'm not very likely to get a pluggable solution to
that - but some tips what people use to create indices, and how they deal
with updating issues.

Interesting for ZOPE-related stuff, but the actual part of building and
evaluating a query is handled by my little language. From what I understand,
AdvancedQuery only enhances the expressional strength of queries against
ZCatalog.
