Using IR_AND_OR_QUERY and ^NQ

Hi Community

I have a question about building queries in knowledge query using both IR_AND_OR_QUERY and ^NQ

When building the query everything works fine except that when adding ^NQ nothing is shown.

Both parts of the query works separetly but when using the ^NQ non of them works.

The first part the "groups" and "comp" are arrays and the "available for" fields glidelists

I want to return results where the user is either member of a chosen group or the user have relation to a chosen company OR articles where both the lists are empty

var str = current.getEncodedQuery().toString();

var search2 = str.search('IR_AND_OR_QUERY');

var subStr = str.substring(search2, str.indexOf('^', search2));

current.addEncodedQuery('active=true^workflow_state=published^u_available_forLIKE' + groups + '^ORu_available_for_companiesLIKE' + comp + '^language=javascript:gs.getUser().getLanguage()^' + subStr +

'^NQactive=true^workflow_state=published^language=javascript:gs.getUser().getLanguage()^u_available_for_companiesISEMPTY^u_available_forISEMPTY^'   + subStr);

So the question is, if im doing something wrong with the search somehow that i cant see myself or maybe i misses some functionality with IR_AND_OR_QUERY and ^NQ

Thanks
