Query facet count and its matching documents

[Gnanakumar <gn...@zoniac.com>]

Hi,

We're running Apache Solr v3.1 and SolrJ is our client.

We're passing multiple Arbitrary Faceting Query (facet.query) to get the
number of matching documents (the facet count) evaluated over the search
results in a *single* Solr query.  My use case demands the actual matching
facet results/documents/fields also along with facet count.

My question is, is it possible to get facet query matching results along
with facet count in a single Solr query call?

Regards,
Gnanam

Any ideas on this?

nope .. there's nothing in Solr to give you these results in a single 
query -- you could write a component to do something like this, but you'd 
have to think about how you want to deal with the fl/start/rows of these 
extra queries.

Note: one thing you can do with the psudo-fields feature of Solr 4.0-ALPHA 
is include a psuedo-field with each document in the main result 
set indicating it's score from arbitrary queries -- including tose queries 
you are using in facet.query.

Something like this works with the Solr 4.0-ALPHA example data...

http://localhost:8983/solr/select
?q=*:*
&apple=name:apple
&electronics=cat:electronics
&facet=true
&facet.query={!key=apple v=$apple}
&facet.query={! key=electronics v=$electronics}
&fl=id,electronics:query($electronics),apple:query($apple)
