Hello,
Quoting http://wiki.apache.org/solr/SolrCaching#filterCache :
The filter cache stores the results of any filter queries ("fq"
parameters) that Solr is explicitly asked to execute. (Each filter is
executed and cached separately. When it's time to use them to limit
the number of results returned by a query, this is done using set
intersections.)
Finding what best suits your needs probably depends on how field1:val1
and field2:val2 vary all together, ie wether there exist a correlation
in issuing field2:val2 knowing that field1:val1 was issued (or the other
way)
Hope this helps ;-)

Hello,
Is there any difference in the way things are stored in the filterCache if
I do
&(fq=field1:val1 AND field2:val2)
or
&fq=field1:val&fq=field2:val2
eventhough these are logically identical ? What get stored exactly ? Also
can you point me to where in the Solr source code this processing happens ?
Thank you.
Antoine.
