If both parameters are null, result will be null. If one parameter is null and the other parameter is not, the non-null parameter will be returned. Equally, if the FilterExpression of both parameters are null, empty or only whitespace, then the result will be null. If one parameter has a filter expression that is null, empty or whitespace and the other parameter's filter expression is defined, then the parameter that has a filter expression will be returned.
