Disabling items in search (time)

Question

When I disable a list from appearing in a search, does this:

1. Take effect immediately
2. Require a crawl
3. Take an unspecified amount of time
4. Other

I have a reference list that is appearing in search and throwing users off, I would just like to see if I need to do a crawl or not. If a crawl is required, should it be a:

1. Full Crawl
2. Incremental Crawl

Answer 1

You need to do a crawl, as the item will need to be deleted from the index if it was there previously, and it's the crawler that does this.

An incremental crawl should do the trick; if you want to be super-sure and don't have that much searchable content, you could also do a full Index Reset then a full crawl.

Answer 2

Yes, it requires performing incremental Crawl. it's enough to reflect your new list search settings.

Incremental crawl covers the below scenarios,

• Adding new document/item.
• Edit document/item Content, Properties / Delete document/item.
• Changing List / Library settings.
• Changing Item permissions.
