Searchers and segments

I just want to confirm something I assume is true.

A Searcher will returns results only for the segments of the index that
existed at the time the Searcher was created.

I.e., if I add/update/delete documents from an index, any opened
Searchers are stale and should be destroyed and re-opened, yes?

I added the following clause to IndexSearcher's docs in an attempt to address
this question:

 * IndexSearchers operate against a single point-in-time view or
 * L<Snapshot|KinoSearch::Index::Snapshot> of the index.  If an index is
 * modified, a new IndexSearcher must be opened to access the changes.
