LazyPagingItems not collecting for LazyVerticalGrid with Search Query Funtional Paging 3.0 Jetpack Compose - state

Question

I want to update list from paging with search query result,basically I had success to display item paging to lazyverticalgrid without searchQuery variable. The problem is when I click search button from keyboard virtual, the items not update in compose
HomeViewModel.kt
#HiltViewModel
class HomeViewModel #Inject constructor(
savedStateHandle: SavedStateHandle,
private val productRepository: ProductRepository,
private val dataUserDao: DataUserDao
) : ViewModel() {
private val _searchLiveData = savedStateHandle.getLiveData("search", "")
val searchLiveData: LiveData<String> get() = _searchLiveData
private val _productList = MutableStateFlow<PagingData<Product>>(PagingData.empty())
val productList = _productList.asStateFlow()
init {
getDashboard()
getBanner()
searchProduct("") // this work!
}
fun searchProduct(s: String) { // when this execute again with value the product list not recomposed
viewModelScope.launch {
productRepository.getProducts(0, s, "", "").collect { data ->
_productList.value = data
}
}
}
The collectAsLazyPagingItems function for product list is work when search query is empty, but when search query is not empty collectAsLazyPagingItems function is not triggered
