[Zope-CMF] Wondering about catalog tool bloat

[Alec Mitchell]

It seems to me that the default CMF catalog tool is a bit bloated.  My main 
concern is that FieldIndexes are used for Date, created, effective, modified, 
start, and end (the last two created by CMFCalendar), when they should 
probably all be DateIndexes.  Plone has already made some of these changes, 
but it would be nice to have it in the CMF itself.  Also, what is the purpose 
of the metadata redundancy between ModificationDate and modified or Date and 
CreationDate (which are also redundant in the indexes)?

Thanks,
