OK, then I don't think it's a Solr problem. I think 5 of your Tomcats are configured in such a way that they consider ^ to be an illegal character.
There have been recurring problems with Servlet containers being configured to allow/disallow various characters, and I think that's what's happening here. But this is totally outside Solr. Solr, when it successfully distributes a query, sends the query on to one replica of each shard, and I was wondering if that process wasn't working correctly somehow, although boosting is so common that it would be a huge shock since it would have broken almost every Tomcat installation out there. By sending the query directly to each node, you've bypassed any forwarding by Solr so it looks like the problem is before Solr even sees it. So my guess is that somehow 5 of your servers are configured to expect a different character than the server that works. I'm afraid I don't know Tomcat well enough to direct you there, but take a look here: https://wiki.apache.org/solr/SolrTomcat Sorry I can't be more help Erick On Wed, Dec 24, 2014 at 1:33 AM, S.L <simpleliving...@gmail.com> wrote: > Erik, > > The scenario 1, that you have listed is what seems to be the case. > > When I add distrib=false to query each one of the 6 servers only 1 of them > returns results (partial) and the rest of them give the illegal character > error . > > I have not set up any special logging I do not see any info in the > catalina.out but in a file called localhost_access_log.2014-12-24.txt in > tomcat/logs directory, I see the following logging message when the invalid > character error occurs. > > [24/Dec/2014:09:25:54 +0000] "GET > /solr/dyCollection1_shard2_replica1/xxxxxxxx?fl=*,score&q=canon+pixma+printer&sort=score+desc,productNameLength%20asc&wt=json&indent=true&rows=100&defType=edismax&qf=productName&mm=2&pf=productName&ps=1&pf2=productName&pf3=productName&stopwords=true&lowercaseOperators=true&bq=hasThumbnailImage:true^2.0&distrib=false > HTTP/1.1" 500 7781 > > I am using Tomcat 7.0.42 and SolrCloud 4.10.1 and the Oracle JDK . > > java version "1.7.0_71" > Java(TM) SE Runtime Environment (build 1.7.0_71-b14) > Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode) > > Thanks. > > On Tue, Dec 23, 2014 at 11:46 AM, Erick Erickson <erickerick...@gmail.com> > wrote: > >> Hmmm, so you are you pinging the servers directly, right? >> Here's a couple of things to try: >> 1> add &distrib=false to the query and try each of the 6 servers. >> What I'm wondering is if this is happening on the sub-query sent >> out or on the primary server.
