[Zope-CMF] Search results with portal_catalog - need a strategy

[Peter McMillan]

I have what should be a simple objective. I'd like to search on the indexes
of Title, Description and Summary. I have 191 documents in the site.

When I search, I'm returning all 191 documents. I should be getting a
smaller search result. If someone could give some pointers, I'd appreciate
it. 

I'm using the stock search facilities within the Portal (Zope 2.5.1/CMF1.4).

My indexes:
Date                    FieldIndex
Description         KeywordIndex
Subject               KeywordIndex
Title                      KeywordIndex
Type                    FieldIndex
Bobobase_modification_time  FieldIndex
Id                          FieldIndex
Meta_type              FieldIndex

Thank you,

Peter
