DisMax query parser syntax for the fq parameter
Hello,
I am using the dismax query parser syntax for the fq param:
.../select?qt=dismax&rows=30&q.alt=*:*&qf=content&fq={!dismax qf=contentKeyword^1.0 mm=0%}Foo&fq=+date:[2009-03-11T00:00:00Z TO 2009-07-09T16:41:50Z]&fl=id,date,content
Now, I want to add one more field to the qf parameter:
...&fq={!dismax qf=titleKeyword^1.8 contentKeyword^1.0 mm=0%}Foo&...
=> Solr should return a doc, if "titleKeyword" OR "contentKeyword" contains "Foo".
But this results in an error:
SEVERE: org.apache.solr.common.SolrException: org.apache.lucene.queryParser.ParseException: Expected identifier
at pos 43 str='{!dismax qf=titleKeyword^1.8 contentKeyword^1.0 mm=0%}Foo'
Is it possible to use the fq filter for multiple fields?
Thanks
Gisto

The issue is that qf needs to have spaces in it, but the local params
can't deal with that. So what you can do is fq={!dismax qf=$fqqf
mm=0%}Foo&fqqf=titleKeyword^1.8+contentKeyword^1.0 - hope that works
(just typing that without trying it).
