[jQuery] [autocomplete] How to send the partial word typed by user to ajax url?


Hello Gurus,
Is it possible to send the partial word typed by user to ajax url in
bassistance.de/jquery-plugins/jquery-plugin-autocomplete/? This will
help me to use the sql syntax - select abc from tab_name where abc
like "%user_word%" and limit the results to speed up.
Also, I have a select drop down. I want to pass on the value of
currently selected item (e.g. country) to the ajax url. How can I do
this?
Thanks.
