: class:100
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.
