You might consider searching the list of recipes instead. If you find a recipe that matches the name of the package you want:
Add the layer providing the recipe to your project
Build the recipe
Once the build completes, come back to this page and search for the package
{% url 'recipeselectpackages' project.id recipe.id as xhr_table_url %}
{% with 'recipeselection' as table_name %}
{% with 'Add | Remove packages' as title %}
{{title}} ()
{% include "toastertable.html" %}
{% endwith %}
{% endwith %}
