Thanks Sascha for your post, but i find it interresting, but in my case i don't want to use an additionnal field, i want to be able with the same schema to do a simple query like : "q=res_url:some url", and a query like the other one; in other word; is there any solution to make two or more multivalued fields in the same document linked with each other, e.g: in this result:
- <result name="response" numFound="1" start="0"> - <doc> <str name="id">1</str> <str name="keyword">Key1</str> - <arr name="res_url"> <str>url1</str> <str>url2</str> <str>url3</str> <str>url4</str> </arr> - <arr name="res_rank"> <str>1</str> <str>2</str> <str>3</str> <str>4</str> </arr> </doc> </result> i would like to make solr understand that for this document, value:url1 of "res_url" field is linked to value:1 of "res_rank" field, and all of them are linked to the commen field "keyword". I think that i should use a custom field analyser or some thing like that; but i don't know what to do. but thanks for all; and any supplied help will be lovable.
