In case of altering filter condition, both results, i.e. for original filter condition and for altered filter condition, should get cached

1. Lets say we added a filter Qtr in [ "Q1", "Q2" ], first time it will fire a query and store result in memory
2. Now apply filter condition Qtr in [ "Q1", "Q2", "Q3" ], now it will compare it with last condition and fire query only for only "Q3" and merge new result with previous result.
   Now in this case both results, i.e. new results for only Q3 and merged result for Q1, Q2 and Q3 should be cached. Right now only new result is getting cached.
