Hi Oli
The issue is probably related to what version of Rails you're using
(and how long ago you installed Thinking Sphinx).
To make STI searches work correctly, Thinking Sphinx forcefully loads
every model when the rails app is started - but this process hasn't
always been in place, and sometimes isn't so friendly for older Rails
versions.
To make sure everything's happening as expected, might be best to add
the following line to the bottom of your environment.rb file:
ThinkingSphinx::Configuration.instance.load_models
Cheers
