Search or Ask on the main search component of the site

I'm looking for the right pattern to support 'asking' more questions to our site community from the main search component, I'm looking for a way to combine the main search functionality which involves autocompleting to also have a way for the user to ask and then take his question and present it to him in the 'add a question' page automatically, are there any sites that combines search and ask CTAs on the same main search component? any conventions for that? I thought of adding a toggle on the right of the search area, one will be 'search' and the other will be 'ask' but then I won't have a place for the actual CTA of performing the search, I could assume that people will hit the return for it but I'll still need to have an action button.I'll be happy to learn from your suggestions. thanks.
