Improved search performance in the modern interface

The search performance in the Windows Client modern interface is seriously impaired due to having thousands of unique applications in our environment.
As soon as you type the first character it can be searching all our Published Apps the application can freeze and fail to accept any additional character input.

We don't see this issue in the Classic interface, but the classic interface doesn't show the parent folder of search results.

Is it possible to improve the search in the modern interface, so that search only begins after pressing enter key? or a time delay option so search only begins 1.5s after the last character was entered in the search box.
