[Zope-CMF] Searching portal_catalog using wildcards or regexp

[Kevin Carlson]

Thanks, Chris.  This works fine.  I am curious as to whether or not the
catalog will support regular expression searching in the future since adding
a new index to the catalog each time we want to program a new search method
seems a bit cumbersome.  I understand the overhead involved with regexp --
even something similar to a LIKE operator in SQL would be nice.  Thoughts
anyone?

Kevin

1. Create a FieldIndex called 'Title_firstletter'

2. Create a Script (Python) called 'Title_firstletter' and put it in your
skin:

title = context.Title()
return title and title[0] or ''

3. re-index everything

4. perform your search like:

results = context.portal_catalog({'Title_firstletter' : 'A'})

cheers,

Chris
