RxSearchView after cleaning with backspace

Question

I have RxSearchView:

RxSearchView.queryTextChanges(searchView)
            .filter(charSequence -> !TextUtils.isEmpty(charSequence))
            .debounce(600, TimeUnit.MILLISECONDS)
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(query -> {
                Toast.makeText(this, query, Toast.LENGTH_SHORT).show();
            });

When I search word test the Toast shows me test, after that I would like to clean searching text using backspace, and the problem is when the search is empty in the Toast appears with text t.

How to solve this problem ?

I was trying to use .filter(item -> item.length() > 1) but this doesn't work too, in that case Toast appears with text te

Answer 1

The problem was in sequence. debounce must be before filter

This will work:

RxSearchView.queryTextChanges(searchView)
            .debounce(600, TimeUnit.MILLISECONDS)
            .filter(charSequence -> !TextUtils.isEmpty(charSequence))
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(query -> {
                Toast.makeText(this, query, Toast.LENGTH_SHORT).show();
            });
