@LCL ,
1- you mentioned a slow query and @vnium suggested a way to re-write the same query. Could you confirm, that the suggested approach is working for you?
Searching for type “Parameter” and then filtering on key value is more CPU intensive than directly using the key index and searching using eq() function. @vnium suggestion should really improve your query perf.
2-Could you elaborate on your other queries when you mentioned “I go one level further”? (A sample querie may help). Thanks
