Public bug reported: Problem ----------- Every time the user changes the content of the search-bar the Dash updates its result-view. When typing, this results in result-view screen flickering.
Common solution for this problem ----------------------------------------------- Is to cache the last user-input and search only after a delay, as long as there has been no new user input. This function is called 'Debounce' in ReactiveX -> http://reactivex.io/documentation/operators/debounce.html Pros: * less screen flickering * less resource usage (the search-query is often executed only once) Cons: * very slow search results take from a user point-of-view longer, because they get executed after the debounce-delay.
