Suppose I have an object with the following interface: IArtFile author: TextLine... subject: Textline... location: TextLine...
I setup 3 text indices and create 3 adapters implementing ISearchableText to extract each field. I want to create a search viewlet or page with a <form> section containing [search field author, name & id = author] [search field subject, name & id = subject] [search field TextLine, name & id = subect] I thought about using a class derived from BaseForm or something like that to use the practical Fields(IArtFile). What is the best class to derive from? Then I have somehow to instruct the ICatalog Utility to combine the result from the indicies, I mean if subject is "David" and author "Michelangelo" and location "Firenze", I want all the istances implementing IArtFile having these text lines in their attributes. I was thinking about converting the list returned by each catalog.apply function into set and then calculating the intersect function. Is there a better way to do it? _______________________________________________ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
