When a page has been reached from a search, rather than having a fixed location, is there any benefit to presenting a button to take the user back to the specific search they were in (and their location/page within those results)? Such a button would basically duplicate the behaviour of the browser's back button, but would users benefit from a clearly visible button for it?
Clarification: This is an internal, faceted search, not google. And these are pages which will only ever be reached through search since they have no fixed location in the site's menus (there are too many of them), so there won't be multiple versions of the page.
