That implies that you’re using two different queryParsers, one for the “q”
portion and one for the “fq” portion. My guess is that you have solrconfig
/select or /query configured to use (e)dismax but your fq clause is being
parsed by, the LuceneQueryParser.
You can specify the parser via local params, i.e. fq={!edismax blah blah}query
terms.
Add &debug=query to your input and you’ll see exactly which parsers are used
for what parts of the query.
