Hi everybody, I have a ZCatalog with a lot of indexes on boolean fields. If I query it from DTML, it returns correctly the results of a query like the SQL "SELECT xxxx WHERE (A=0 AND B=0 AND C=1)" I'd like to query it from DTML, obtaining the results as from the SQL query "SELECT xxxx WHERE (A=0 OR B=0 OR C=1)" How can I get that? Or where can I find infos about that? Mik

This is a limitation of ZCatalog right now. A way to "simulate" ORs on different indexes right now is to concatenate the search results ala: Catalog(A=0) + Catalog(B=0) + Catalog(C=1) However you may get duplicates in the results. A better workaround for this is to create an index that contains the calculated value and query on it. For instance, create a python script either in your ZClass or above the indexed objects called "A0orB0orC1" tha does this: return context.A=0 or context.B=0 or context.C=1 Then create a separate index on A0orB0orC1. -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
