What you want to do is display only the suggestions that apply for the given input. Not all possible strings.

Lets assume you have the following AutoSuggestBox:

<AutoSuggestBox 
   TextChanged="AutoSuggestBox_TextChanged"
   SuggestionChosen="AutoSuggestBox_SuggestionChosen">
    <AutoSuggestBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding}" />
            </StackPanel>
        </DataTemplate>
    </AutoSuggestBox.ItemTemplate>
</AutoSuggestBox>

These are the event handlers:

private void AutoSuggestBox_TextChanged(AutoSuggestBox sender, AutoSuggestBoxTextChangedEventArgs args)
    {
        if (args.Reason == AutoSuggestionBoxTextChangeReason.UserInput)
        {
            // You can set a threshold when to start looking for suggestions
            if (sender.Text.Length > 3)
            {
                sender.ItemsSource = getSuggestions(sender.Text); 
            }
            else {
                sender.ItemsSource = new List<String> { };
            }
        }
    }

All you have to do is to write a getSuggestions(String text) method that returns plausible suggestions for a given input.
