Strange things happen when I query with many facet.prefixes and fq filters

Hi,

I'm having issues when running the following query, which is produced by expanding several hierarchical facets (implemented the facet.prefix way).  I realize it's pretty massive, but I'd like to figure out what exactly is causing the problem.  Is it too many facet.prefix clauses, too many fq filters, the combo of both, or what.  Anyway, here is the URL I start out
 with:

mp;f.BKL_Molecular_Mechanism_Associations.facet.prefix=1%2FCardiovascular+Diseases%28MESH%3AD002318%29

The above works fine.  It's basically a bunch of fq= and facet.prefix= parameters.  However, if I add another parameter, shown below, then I will instantly get a totally blank page, and I can't get it to load anything no matter what.  (the parameter itself is fine since it works by itself or with fewer parameters)

&f.BKL_Diagnostic_Marker_Associations.facet.prefix=3%2FCardiovascular+Diseases(MESH%3AD002318)%3BArteriosclerosis(MESH%3AD001161)%3BAtherosclerosis(MESH%3AD050197)

Here's another interesting thing: if I just add the parameter field without any value, as in "&f.BKL_Diagnostic_Marker_Associations.facet.prefix=", then I will get a page of the result, but without any CSS rendering.

Please advise what may be going on here.  Is my query simply too big?  Does Solr have a limit?  Did I break the limit?

Ah, thanks for bringing closure. Should have occurred to me
when I saw your query....

Good question.  I checked the output sent to Jetty.  In the case where it returns a blank page, nothing at all is sent to Jetty.  This raised my suspicion that Solr never got a chance to process the query.  Sure enough, it led me to the finding that Jetty by default cannot take more than 4 KB of header.  After I increased that limit, everything works.
Problem solved.

The very first question I have is "what do your Solr logs show"? I suspect
you'll see something interesting there. Otherwise, there's no way really to
say what's going on here without reproducing your setup...

Re: Strange things happen when I query with many facet.prefixes and fq filters

Posted by Erick Erickson <er...@gmail.com>.
The very first question I have is "what do your Solr logs show"? I suspect

say what's going on here without reproducing your setup...
