I have some document libraries that I wish to use for file archival purposes for older files that don't need to be accessed on a daily basis, but still need to be kept for posterity. Because these files don't need to be regularly accessed, I'd like to hide them from showing up in searches across the whole site collection, so that they don't clog up the search.
However, setting this option to "no" also disables search from working within the document library after a couple of moments. This makes it impossible to find files within search disabled document libraries when the need arises.
Is there any means of hiding the contents of a document library from a site collection wide search while still having search available within the document library?
