[Zope-dev] Needed: tip iterative search of catalog indexes

Can anyone provide advice for iterating a search through all indexes in a catalog. E.g., determining whether 'foo' appears in any field of any of the indexed items. The python method reproduced below does the job, but it seems rather cumbersome. Is there a better way to do it in DTML? Thanks. --------------------------------------------- list = [index1, index2, ... ] return self.Catalog({list[0] : search_item}) for item in list[0:]: for result in self.Catalog({ item : search_item}): if not result in results: results.append(result) return results
