Hello, I've been working away on an application, and it's now starting to take shape, based around a series of content objects. As recommended on this list I opted for Zope 3 to build my app, and I'm finding it quite powerful. However, I've hit a bit of a brick wall around searching. It seems from the documentation that ZCatalog is the prefered way of doing a search in Zope 2, but that this isn't implemented in Zope 3. I've got Philipp von Weitershausen's (very good!) book, and he doesn't implement a search for his recipe objects. I've also been looking at the PDF of the Zope 3 Book (which I've also found really useful) and I haven't spotted searching of objects mentioned in that. My search tool will need to take various criteria (say, number of bedrooms, maximum rent, areas the property can be located in) and scan through my objects to find all the matches. I think I can work out how to search through the objects themselves in order to find the matches, the real problem is taking in the criteria in the first place. (Although, any tips provided on the searching side of things would certainly be welcome too!) As a 'dummy run' at searching I created a View for my PropertyFolder object that shows properties based on specified criteria - I can get this to work OK, but I have to put the criteria right into the Python code, so clearly that's not acceptable... I would be grateful for anything anyone could point me to that would help me to build a tool to search my content objects. Philipp mentions the use of Utilities for searching, but beyond that, I don't know where to start. Is it possible to use Interfaces to create data entry schemas/forms for Utilities in the same way as for objects? Any help, greatly appreciated.
