The big deal is that option only allowed RANGE and only OR chain..in fact this:
find_by_solr "query-string AND (id:(1) OR id:(42))" work.. (so I've been told) and logically talking it does the right thing..in only search for query-string among the subset of ids.. but..is this the only way?..so ugly? the guy who tried this moreover said that this fails often in production..probably due to the high number of ids..
