   Hi @pdeva, the answers to your questions are,
   
   1. A time filter looks like `__time >= TIMESTAMP '2000-01-01 00:00:00' AND __time < TIMESTAMP '2000-01-02 00:00:00'`. This syntax adheres to the SQL standard.
   2. If you group by a `TIME_FLOOR` function, that's like specifying granularity (this is mentioned in the docs under "Query execution" where it says we'll use timeseries if we can for this function).
   3. Not sure what you mean by this?
   4. Not sure what you mean by this?
   5. They are undocumented, but they won't be for long. http://druid.io/docs/latest/misc/math-expr.html might help you understand what they're doing.
   
   I agree an examples section would be nice; @jon-wei was working on some new tutorials for querying, maybe he can chime in with whether he had planned on adding SQL examples.
