[Zope] ZCatalog: underscore ("_") character is a separator

Hi, Right now the underscore character is a separator in full-text index of ZCatalog. Does this seem reasonable? I have many variables that are named with underscores (like product_number, product_id, etc.) and ZCatalog cannot find the objects containing these texts. Wouldn't it be more appropriate NOT to treat the underscore as a separator? At this moment, which file do I have to modify to eliminate the underscore as a separator? (or equivalently, to make it a valid character.) thanks, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
