In an entity search, have an Integer Number field and want to filter results to include multiple values… I want to return the entities with values: 123 and 651… I am using a filter expression:

[["formulanumeric: case when {custentity_my_int_field} in (123,651) then 1 end", "equalto", "1"]]

This works fine, but I am curious if there are any other known solutions which may perform better..
