I having grails criteriaQuery where I am checking OR logic againist a single state variable like this:
criteriaQuery
OR
or { eq(\"status\", Status.
You can use
'in'( "status", [Status.ONE, Status.TWO, Status.THREE] )
Or just
'in'( "status", Status.values() )
if Status is an enum with values ONE, TWO & THREE.
Status
