Numeric comparison operators in GridView searches?

Okay, my last newb question for the day (I promise).

Is there a way to enable using numeric comparison operators in the GridView search for fields that are numeric?

For instance, in my employees table, we have an hourly_base_rate field which is a decimal (float that represents a dollar figure). It would be fantastic if one could enter something like:

>= $50.25

and get all employee records where the hourly_base_rate is $50.25 or more.

I noticed the following issue in github:

Comparing operators like >,< >=,<= to search in GridView

and the following PR associated with it:

Query helper method for filter values containing operators

But if it was implemented, I haven’t been able to make it work.

Thanks,

S.
