Prevent Old Search Responses from Replacing New Results

Example: a short query beats its longer version

A reader types “form” and then “forms”. The later request returns first. If the “form” response arrives afterward, the interface must not replace the newer results merely because that response was successful. The same rule applies to a delayed error from an obsolete request.

Test cancellation and recovery

Clear the field while a request is in flight, change a filter quickly and navigate away. Verify that loading status ends correctly and that an obsolete response cannot repopulate a cleared search.

Show the active query near its results when useful. Predictable state matters more than making every keystroke immediately trigger a network request, especially when the source is slow or rate-limited.
