[Replace the criteria value on lookup] check box on Query page was added from PU12 in order to fix the issue that entered string and chosen value are combined.

But after turning on [Replace the criteria value on lookup] check box, user can enter only one value for one criteria.
But customers need to enter multiple values for one criteria very often.
End users do not want to turn on/off the check box frequently.

Could you please fix the combined string issue without using the check box?
