Shot in the dark: perhaps you have a doc w/o a value in the description field, which means the xsl:variable's select doesn't match anything; which perhaps means that your XSLT engine then leaves the variable undefined.

I've been : doing some upgrades to Java & Solr and I'm trying to narrow down where the : problems are happening. : : I have a few XSLT docs that I put into the conf/xslt directory for my : indexes I haven't changed the in a while, and they were working fine for a : 3.X Solr, and seemed to work fine on an earlier 4.X release. : : The problem is that sometimes I get an error saying that a field can't be : found.
