Questions about boosting

[Shawn Heisey]

I've been trying to figure this out on my own, but I've come up empty so 
far.  I need to boost documents from a certain provider.  The idea is 
that if any documents in a result match a separate query (like 
provider:bigbucks), I need to multiply the score by X.  It's important 
that the result set of the actual query is not changed, just the order.

I've tried a few things from the relevancy page on the wiki but so far I 
can't seem to get anything to work.  What syntax should I be using?  Is 
it possible to do this at query time?

Thanks,
Shawn
