Capability to apply a "nosearch" tag to a node which prevents it from showing up in a search result

It wouldn't be that hard to add the functionality to search config. I can't make my mind up about whether or not that might be better off as its own module.

I think this would be a nice feature, bumping to 7.x

@paulbooker come to think of it, I think it's probably easier to accomplish this using the search filter provided by the views module.

I think that a no search flag with its' own db table would be the most efficient method of doing this (a minimal overhead join)

Is it best to maintain a double level here?

[ ] Exclude from all searches
[ ] Restrict to users with "Bypass search restrictions" permission

The first option excludes it completely from the search index and the second only excludes it from users that do not have the permission.

Thoughts?

Cross posting to #399822: Merge in features from Restricted Search (search_block) which is similar / older.
