Hi, I'm in the process of integrating a 3rd party search engine with Zope and have a question about being able to make this work. I'd like to use the spidering capability of this search engine for it to build it's own index. What should the most ideal approach be? 1) Should I write an object in Zope that will interface between the search engine and the objects in Zope? For example, writing an object that uses a script that the search engine could call to Plone to return a list of objects of type 'documents' that were modified in a given range of time. 2) Should I write an object in Zope that will make calls to the Zcatalog to get back simliar results in 1)? I'm concerned about having to manage both the ZCatalog and the 3rd-party search engine's catalog. There may also be performance issues to consider.
