Multiselect field in search

Not sure if this is a bug or working as designed:

We’ve got a multiselect field. If we add this field to search and set Field Input Type = Select, it is being rendered as a single select menu.

That doesn’t seem to make sense to me, as the purpose of a multiselect field is to select multiple options in search and have them combined with AND/OR.

If this is the expected behaviour, I’d like to suggest to change that so a multsiselect field is actually rendered as a multiselect.

Right now, the only option seems to be to set Diplay Type = CHECK which isn’t ideal if the field has many options; being able to use Select2 search feature would be a lot better.
