[Zope] search: question

Hello zope users, I need your help with search capability. I have wrote custom zpt pages with some python scripts and zsql methods. Page templates are for reporting needs to show statistics about clients. All data about clients are stored in relational database. I want 'search box' to search in my database too. What should I customize/write to implement this? Or maybe there is better approache? (should I write separate script to do search in db and not to touch standard search?) Any help, suggestions are very appreciated. Thanks in advance. Best regards, Ruslan mailto:alienoid@is.lg.ua
