Add product characteristics in search pool

Add product characteristics in search pool

I have a question regarding the search module. Is it possible when searching for products to include product characteristics in the search pool? I don't need to search based on characteristics (administrator/index.php?option=com_jshopping&controller=config&task=catprod), I want to search not only in product names and description, but in product characteristics as well.
Let me know if you don't understand my question properly.
Thank you for your help!

Aw: Add product characteristics in search pool

Even Joomla's own search module + joomshopping search plugin don't include the characteristics in the search pool. Any help will be much appreciated.
