Guys, currently it is impossible to do scan query and filter by 2 or more fields. All I want is to have pretty simple logic on WebConsole that will create a predicate to filter the data based on user provided field names, values and operations. This is what we can have really fast and will be very handy if cluster does not have SQL configured.
Vladimir suggests generic approach which makes sense to me, but will require much more effort and time. --Yakov
