When searching for picklist values with “is” and “isn't”, it is possible to specify values that do not exist. See “1-1.png” and “1-2.png”.
It is also very confusing because the non-existent value I am typing is displayed as if it were a search result. Please see “1-3.png”.
When searching picklists or multi-picklists with “is” or “isn't,” if a non-existent value is entered, “No match found” should be displayed in the search results to prevent the entry of a non-existent value.
It is a common behavior that if a non-existent value is entered in module searches such as “3.png” when creating a report, “No match found” is displayed and the non-existent value cannot be entered, so we would like this to match this very common behavior.
