Searchbox doesn’t autocomplete

Great plugin!

But I’m having issues with the “searching by text” extension.

1) It doesn’t autocomplete like on your demo site. I have to hit search-button to run to search.
2) It seems like you need to enter complete words to find matches. You will find the match for a product called “D-vitamin” if you search for “vitamin” but not if you search for “vitam”. Is this a bug or how it is supposed to work?
3) I can’t find the settings/options view you show here http://www.woocommerce-filter.com/extensions/
