Using "OR" in a screener query requires caution because "AND" takes precedence over "OR". The outcome of your query can vary significantly depending on how you use brackets to group conditions.

For example: 

(Net Profit TTM Growth %  > 15  OR 

 Net Profit QoQ Growth %  > 20)  AND 

 ROE Annual %  > 40    

This yields 134 results, as the brackets limit the “OR” condition to just two filters: Net Profit TTM Growth% and Net Profit QoQ Growth%.

Now, if you run the same query without brackets:

Net Profit TTM Growth %  > 15  OR 

 Net Profit QoQ Growth %  > 20  AND 

 ROE Annual %  > 40 

This returns 300+ results because without brackets, “OR” applies to all subsequent conditions, making them optional.
