[Zope-dev] ZCatalog hackery

Will the new data be 'made ready for indexing' before it is compared to the
existing data?  That is, will ZCatalog have to compute the data in some
way before it compares it to what is already stored?

I'm wondering because it would be significant overhead to 'make a data field
of 100MBs into an index-like value' and then compare it to what already
exists in the ZCatalog.

Thanks,
