[Zope] ZCatalog Confusion Solved

[James W. Howe]

Recently I posted a question about why my ZCatalog search wasn't behaving 
the way I had expected.  I was trying to find items with had a particular 
meta-type and particular values for a couple of ZClass properties.  It 
turns out that I had defined the properties in the Meta Data Table but I 
didn't define them as field indexes in the Indexes area.  I assume that 
since I hadn't specified my properties as indexes, when the catalog search 
was performed it simply ignored those values and only used the meta_type 
specification and this is why all items were returned rather than the one I 
expected.  When I added the field indexes the search behaved as expected.

A careful re-reading of the ZCatalog tutorial helped me solve this one.
