Working with ranges and select options in ABAP with HANA

Hi People,

Maybe this question has has been asked before but I couldnt find it. Im looking to optimize a custom report that uses Open SQL mostly. Now the current SELECTs work with ranges. And there isnt much business logic other than the SELECTs.

If i mean to optmize this further, how can I best do it?

Say I have a SELECT from table A where field_1 IN range_1. Can I even optimize this specific query further and if yes how?

I was looking for CE functions that accept ranges as filters while returning results but i didnt see it explicitly somewhere. I checked CE_COLUMN_TABLE and CE_PROJECTION.
