We have two types of result items displayed with SearchTemplate:

1. Real result (e.g., a map object): When the user clicks on it, we display this place on the map.
2. Search suggestion: When the user clicks on it, we intend to update the search query and restart the search.

The bug is related to the second type of result item. When the user clicks on it, we aim to update the search query and present a new query to the user. Unfortunately, calling setInitialSearchText("...") a second time is not working.

Below is a code snippet to reproduce the issue:

import androidx.annotation.NonNull;
import androidx.car.app.CarContext;
import androidx.car.app.CarToast;
import androidx.car.app.Screen;
import androidx.car.app.model.Action;
import androidx.car.app.model.ItemList;
import androidx.car.app.model.Row;
import androidx.car.app.model.SearchTemplate;
import androidx.car.app.model.Template;

public class SearchScreenTest extends Screen implements SearchTemplate.SearchCallback
{
  @NonNull
  private String mQuery = "Initial text";

  public SearchScreenTest(@NonNull CarContext context)
  {
    super(context);
  }

  @NonNull
  @Override
  public Template onGetTemplate()
  {
    final SearchTemplate.Builder builder = new SearchTemplate.Builder(this);
    builder.setHeaderAction(Action.BACK);
    builder.setShowKeyboardByDefault(false);
    builder.setInitialSearchText(mQuery);
    builder.setSearchHint("Search");
    builder.setItemList(createItemList());
    return builder.build();
  }

  @Override
  public void onSearchTextChanged(@NonNull String searchText)
  {
    // No-op
  }

  @Override
  public void onSearchSubmitted(@NonNull String searchText)
  {
    // No-op
  }

  @NonNull
  private ItemList createItemList()
  {
    final ItemList.Builder builder = new ItemList.Builder();

    for (int i = 0; i < 5; i++)
    {
      final String title = "Item " + i;
      builder.addItem(new Row.Builder().setTitle(title).setOnClickListener(() -> {
        mQuery = title;
        CarToast.makeText(getCarContext(), "Search for " + title, CarToast.LENGTH_LONG).show();
        invalidate();
      }).build());
    }

    return builder.build();
  }
}
