Hi all, thanks to Andrea Gazzarini suggestion I solved it using local params ( which is different from macro expansion even if conceptually similar). Local params were available in Solr 4.10.x
I appended this filter query in the request handler of interest: <lst name="appends"> <str name="fq">{!lucene df=filterField v=$allowed_values}</str> <str name="allowed_values">*</str> </lst> This will appear in all the collections request handler that want to use the filter.
