Question about filters and implementing a search function

[GamingCity]

Im trying to learn how to use this lib, it seems to do what i need with filters and sort. On Avalonia UI.

After attaching a filter, you do you tell it that that the information the filter is based on has updated IF the obersable list has not changed?

let say.

[ObservableProperty]
internal string search = string.Empty;

public viewmodelconstructor()
{
      var view = list.CreateView(x => x);
      ItemsView = view.ToNotifyCollectionChanged(SynchronizationContextCollectionEventDispatcher.Current);
      view.AttachFilter(x => x.Name != null && x.Name.Contains(Search, StringComparison.CurrentCultureIgnoreCase));
}

Search is attached to the textbox and i want the displayed list to update as the user writes the search string rather than press a button.

If i use a button and attach the "AttachFilter" to a command, it will work, and i can do the same thing every time "search" string has changed, but not sure if thats the intended way of doing it.

Thank you.
I see, we may need something that can only notify from the outside.
