mProducts = Transformations.switchMap(
                savedStateHandle.getLiveData("QUERY", null),
                (Function<CharSequence, LiveData<List<ProductEntity>>>) query -> {
                    if (TextUtils.isEmpty(query)) {
                        return mRepository.getProducts();
                    }
                    return mRepository.searchProducts("*" + query + "*");
                });

mBinding.productsSearchBtn.setOnClickListener(v -> {
