Autocomplete returns a different url value than Search

I understand that autocomplete is optimized for a quicker search, but why would the results return different urls? Specifically, when configuring your install, the value of the url is different between Autocomplete and Search.

For example, autocomplete returns a url of “…/reference/#keyword” while Search returns a url of “…/reference/” for the same search keyword. Is there a way to not have the standard search strip the section (anchor)?
