Description

toExpression in at least CloudSolrStream concatenates parameters in a comma-separated list. This is fine for things like sorting but incorrect for fq clauses. If my input is something like
fq=condition1
fq=condition2
it winds up being something like
fq=condition1,condition2

I've seen it in this class for this parameter, other classes and other parameters might have the same problem.
