Problem with dismax handler when searching Solr along with field

[farhanali <ar...@gmail.com>]

when i search the query for example 

http://localhost:8983/solr/select/?q=category&qt=dismax

it gives the results but when i want to search on the basis of field name
like

http://localhost:8983/solr/select/?q=maincategory:Cars&qt=dismax

it does not gives results however

http://localhost:8983/solr/select/?q=maincategory:Cars

return results of cars from field name "maincategory"

The dismax handler does not allow you to use lucene query syntax.   
The qf parameter must be used to select the fields to query  
(alternatively, you can provide a lucene-style query in an fq filter).

See the documentation here:
