I love hurry.query. Whether it's in the core or not doesn't phase me,
but it is really really helpful. We got bit by not realizing that
FieldIndex queries passed directly to the catalog/index had a low and
high range. It was a small bite. But it took us a while to figure out
why searching for 'summer' pages included 'winter' ones, but searching
for 'winter' pages only returned winter. So we put in hurry.query. And
were able to do it without depending on zc.catalog. It made the
catalog experience a lot nicer.
I'd put my vote behind inclusion. While the catalog is certainly
cleaner and easier to understand than the Zope 2 catalog, querying it
is still kindof a pain, which is mentioned in
This is somewhat problemetic. It means that application
code that calls apply has to be aware of the
expected query type. This isn't too much of a problem now,
as we have no more general query language nor do we have
any sort of automatic query-form generation.
It would be nice to have a system later for having
query-form generation or, perhaps, sme sort of query
language. At that point, we'll need some sort of way to
determine query types, presumably through introspection of
the index objects.
hurry.query seems to fill in this hole.
