Pat might correct me here, but I'm pretty sure the define_index block is only executed when the model is loaded. In development mode this is each request, in production mode it's on app startup. It also shouldn't be instantiating models, it just uses active record associations to define the sphinc config. > > That's what sphinx does directly.

I think you could define your own Delta handler and control this process more if you really need to. Check out my post of custom delat handlers from a few days ago. -- James Healy <jimmy-at-deefa-dot-com> Tue, 01 Sep 2009 12:49:47 +1000 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Thinking Sphinx" group.
