lets say I have 2 checkbox fields. When both boxes are checked/true, I want the search to return null, but when only first one is checked/true, I want to return a specific string if it is true, not just "yes" or "no". whats the best way to do this? I used to have this set up in a drop-down field so the string would just be the value of the field but now basically I have case when {x} = 'T' and {y} = 'T' then null ELSE if {x} is true, 'string' END
