When mutiple facet queries are specified, are they booleaned as OR or
AND?
Neither, if you're referring to &facet.query=...
facet.query's are all appended to the response, like this (in Ruby
response format):
{
'responseHeader'=>{
'status'=>0,
'QTime'=>105,
'params'=>{
'wt'=>'ruby',
'rows'=>'0',
'facet.query'=>['ant',
'lucene'],
'facet'=>'on',
'indent'=>'on',
'q'=>'erik hatcher'}},
'response'=>{'numFound'=>3,'start'=>0,'docs'=>[]
},
'facet_counts'=>{
'facet_queries'=>{
'ant'=>1,
'lucene'=>1},
'facet_fields'=>{}}}
The query was this: ?q=erik%
20hatcher&facet=on&facet.query=ant&facet.query=lucene&wt=ruby&indent=on&
rows=0
on our library metadata which, pleasantly, has copies of both the Ant
book (yes, I'm looking into that JUnit issue, Ryan and Yonik :) and
the Lucene book.
If you mean the filter queries, &fq=... then those are logically
ANDed when multiple are present.
