If your query is arriving on the server correctly, but throwing an exception, adjust maxBooleanClauses in your solrconfig.xml. I'm not sure what the consequences are of making it too large, but we had to adjust it from the default of 1024 to 5000 in one implementation.
Basically, each ID in your query is a separate clause. So, you may have exceeded maxBooleanClauses. -Kevin On Tue, Jun 25, 2013 at 5:15 PM, Jack Krupansky <j...@basetechnology.com>wrote: > Are you using Tomcat? > > See: > http://wiki.apache.org/solr/**SolrTomcat#Enabling_Longer_**Query_Requests<http://wiki.apache.org/solr/SolrTomcat#Enabling_Longer_Query_Requests> > > Enabling Longer Query Requests > > If you try to submit too long a GET query to Solr, then Tomcat will reject > your HTTP request on the grounds that the HTTP header is too large; > symptoms may include an HTTP 400 Bad Request error or (if you execute the > query in a web browser) a blank browser window. > > If you need to enable longer queries, you can set the maxHttpHeaderSize > attribute on the HTTP Connector element in your server.xml file.
