[Zope-dev] Searching a relational database

Hi, How can I search a relational database thru Zope? ( I`m using PostgreSQL 7.0.2 on Linux ). I have a DVD/VHS-organizing project that would be pretty useless if people couldn`t search for movies by entering just parts of the title. Ex. typing alien should show "Alien" and "Alien 3". Can ZCatalog be used for this? If I have a SQL-statement that returns all rows in a database, can ZCatalog index this? What I`m looking for is similar to full-text searching on MS SQL 7.0 etc. Tips, hints or pointers?? Thomas
