[Zope] sql like functionality to query zcatalogs

Hi all, This one has been nagging me. Is there some way to search a zcatalogs indexes using SQL? I have a few thousand objects that have price scattered throughout a site I am building. I am looking the price up in a MySQL database based on the objects id. I am seeking a way of cataloging all the objects ( done ) and search that catalog for objects with prices between a certain range. For example: select * from zcatalog where price > 2.5 and price < 2.75 If not sql, which way would be the most simple to do this? Thanks in advance Joel Jensen.
