: query something like : : http://localhost:8983/solr/select?q=(category:lcd+OR+category:led+OR+category:plasma)+AND+(manufacture:sony+OR+manufacture:samsung+OR+manufacture:apple)&facet.field=category&facet.field=manufacture&fl=id&mm=2
Here's an example of something similar using the Solr 4.3 example data... http://localhost:8983/solr/collection1/select?debugQuery=true&q=%2B{!dismax+df%3Dfeatures+mm%3D2+v%3D%24features}+%2B{!dismax+df%3Dcat+mm%3D2+v%3D%24cat}+&wt=xml&indent=true&cat=electronics+connector+XXXX&features=power+ipod+YYYY the important (un url encoded) params here are... q = +{!dismax df=features mm=2 v=$features} +{!dismax df=cat mm=2 v=$cat} features = power ipod YYYY cat = electronics connector XXXX This takes advantage of the fact that the (default) "lucene" parser in solr can understand the "{!parser}" syntax to create subclauses using other parsers -- but one thing to watch out for is that if your entire query starts with "{!dismax}..." then it's going to try and use the dismax parser for the whole thing, so this won't do what you expect... q = {!dismax df=features mm=2 v=$features} AND {!dismax df=cat mm=2 v=$cat} ...but this will... q = ({!dismax df=features mm=2 v=$features} AND {!dismax df=cat mm=2 v=$cat}) This is a realtively new feature of the solr, in older versions you would need to use the _query_ parsing trick... q = _query_:"{!dismax df=features mm=2 v=$features}" AND _query_:"{!dismax df=cat mm=2 v=$cat}" The important thing to remeber about all of this though is that it really doesn't matter unless you truly care about getting scoring from this resulting BooleanQuery based on the two sub-queries ... if all you really care about is *filtering* a set of documents bsaed on these two criteria, it's much simpler (and typically more efficient) to use filter queries... q = *:* fq = {!dismax df=features mm=2}power ipod YYYY fq = {!dismax df=cat mm=2}electronics connector XXXX -Hoss
