Multiple API calls for same input when user types simultaneously in search box

[Akashs991]

Scenario: User needs to search entries by using search parameter as test in paper autocomplete suggestion

Scenario 1 - User types in letters for test in a millisecond delay. So what happens when we check network tab in developer tools
api/?search=t
api/?search=te
api/?search=tes
api/?search=test
User see suggestion in the drop down and selects any entry

Scenario 2 - User types in letters for test simultaneously. So what happens when we check network tab in developer tools
api/?search=te
api/?search=te
api/?search=test
api/?search=test
User see suggestion in the drop down and selects any entry

Result in both scenario are same, but what happens in the backend is different. Scenario 1 works as accepted but scenario 2 makes 2 api calls with same search input as you can see above like

Is there a solution for the behavior that is happening.
