Question: when you use valueschanges then you need to unsubscribe on destroy, correct ?

[jakubtomas]

Hello, you can improve your function, add distinctUntilChanged() after debounceTime function, This function will not run http with same string in order, (is stupid have twice request with same value in order) . And in switchMap or after SwitchMap is not bad idea to write function startWith([]) , empty array. this automatic set empty array in case when is emptysearch string or no match from http response
