Hi, Thanks for the insight Uwe. I could get it up and running thanks to you. But the query seems to be expensive in terms of time. Please have a look at the gist https://gist.github.com/rmuhzin/6991544
Is there anyway that I can fine tune the filter? Another problem is that it seems cache the filtered result so that the result set is same after I execute the query. Please point me in the right direction.
