On the the Quick Search Field (on first page) and on the Advanced Search, I should type the whole word that I want to search for it, in order to have results. I would like you to inform me, how I am able to have also results by typing a part of the word (instead of the whole one).

For example i want to search the product name "Anatomy" but when i type "Anat" i dont get any results.

On the admin side the frontend.search.defaultmethod value is "Any".
