[Zope-dev] Errors searching ZCatalog

[Itamar Shtull-Trauring]

Every once  in a while our ZCatalog (from CVS) seems to get "corrupted" -
usually one (or maybe more) items cause the following error whenever they
come up in a search for certian search terms.  For example today I seached
for "tomato" (/recipe/manage_catalogView?title=recipe) and got this error:

	Error Type: KeyError
	Error Value: 431

Traceback (innermost last):

KeyError: (see above)

I discovered the entry that causes this, and it seems to be cataloged okay -
i.e. if I'm just browsing the catalog it displays fine, and in some searches
it displays fine.  Only when I search by specific words in the title it
gives an error - and not all words.  Updating the catalog solves the
problem.  It's title is "Tomato Bread Salad", which doesn't seem to have any
wierd characters or anything.
