q Variable with Filter Criteria

Summary

q Variable & Filter Criteria don't work when used together

Content

Hi,

I have an application where I am displaying data from my Sales Cloud in a table. I am using the REST webservice and querying the data using the 'q' variable. Something like "?q=AccountPartyId=<Some Value>." This works like a charm but when I add a filter criteria to the table, the filter criteria does not work at all. I still get the relevant data as defined in my 'q' variable but filter criteria doesn't do anything. If I remove the 'q' parameter, the criteria works properly. So, I can't seem to figure out how to make both of them work together.
