Hi everyone,

The choice between filters and regular 'must' query conditions is  
basically about performance, right?

Because filters can be cached better and don't do scoring.

I'm using the Tire gem, but apparently it doesn't do multiple filters  
at the moment, so I'm thinking of making them regular boolean  
conditions for now.

Cheers,  
Chris

I don't know the API of the Tire gem, but you should be able to combine  
multiple filters using the and|or|not filters (in a similar way to the  
bool query/filter)
