How can I create a search like vbulletin.org?

[joyceleong]

Hi,

I would like to check how can I create the search form at the header that links up to the results upon clicking the search button?

Currently I have a textfield and a "GO" button. But when I input a text for search, and upon clicking the "GO" it was sent to the advanced search with the text instead of diverting it to the search results.

Please advise, thanks.
