Implicitly filter search results by the version currently being viewed
Per ggrossetie's suggestion at the the discussion here:
Once component and version is indexed (#35 (closed)) it looks like it should be possible to restrict the displayed search results to the version being viewed, so that a user who performs a search while looking at one version of a documentation will not unknowingly perform a search, select a result from another version, and be navigated to a different version.
