Subject Re: "start minimal" option even deletes contents whose links are deleted
Date Wed, 24 Dec 2014 06:31:30 GMT
Hi Karl.

Here are what I understand.

Minimal crawl does not do the clean up phase.
The clean up phase removes no-longer-reachable documents.
Even when a link of a page is removed from the root page, minimal crawl is
not supposed to remove the index of the no-longer-reachable page.
If hop count is set to 1, then the no-longer-reachable page should not be
affected because its hop count does not exceed 1.

If I am correct above, then I do not understand why the index of the
non-reachable page is deleted.
