: Could this be a needed capability in Solr? It seems like a problem that : a "-field" operator would help, that simply does not return those : fields.
the broader issues is more complicated then that... http://wiki.apache.org/solr/FieldAliasesAndGlobsInParams there is nothing to prevent people from having "-" at the begining of a field name, so a feature like this would cause problems with that (we're trying to avoid adding any more special markup characters for fields like fl, sort, etc...) -Hoss
