Facets drill down

Hi,

I typically issue a facetdrill down query thus

q=somequery and Facetfield:facetval .

Is there any issues with the above approach as opposed to
&fq=facetfield:value in terms of memory consumption and the use of cache.

Regards
Suajatha

Yes... using fq allows those queries to be cached independently into  
the filter cache.  Combining clauses like you show avoids the cache,  
and also the Facetfield:facetval clause is used in scoring which is  
typically unnecessary/undesirable.
