The Search widget in ArcGIS Experience Builder does not populate a suggestion list of values (domains) when proper labels are typed into the Search bar.

Workaround

In some instances, the query is successful if the entire label is typed as an exact match (case sensitive) or if the first three letters of the label are identical to the 3 first letters of the code and only if, the identical letters are typed into the search box (three or more letters).

The query may also be successful despite the absent suggestion list if, the 'Enter' keyboard key is pressed after typing in the proper label or code. This completes the query action and proceeds to display the proper data points or features.
