You shown us he fieldType "class" but you haven't provide any info about the *field* named "class" -- please verify that it uses fieldType "class" You also didn't provide any details about how your edismax parser is configured (ie: what kinds of defaults and query params are you using) the debugQuery=true output showing what the final parsed query looks like is also kind of important here. https://wiki.apache.org/solr/UsingMailingLists -Hoss
