Hi Lonnie
I'm afraid what you're after isn't possible with *Sphinx*, rather than Thinking
Sphinx - though is an easy enough work-around. Firstly: Thinking Sphinx doesn't
use field weight defaults when you're searching across multiple models, and
part of that is the complexity of combining field weights in the expected
manner, but also: when you're querying across multiple indices, Sphinx doesn't
distinguish between fields from each - there's no equivalent of a SQL database
approach (companies.name vs brands.name).
So, the workaround: the fields need to have different names, and you'll need to
specify the weights when searching.
Hope this helps.
