difference between non-/ shared scopes

Question

can someone point out for me the difference between shared scopes and non-shared scopes?
I think one difference is that shared scopes are available in all site-collections, whereas non-shared scopes are only for one site-collection.

I have seen this question which shows how to programatically (means utilizing the object model) create a shared scope. Is there a way to programatically create non-shared scopes?

Is there any suggested reading on sharepoint-seach for "noobs"?

Answer 1

There are only two Scopes 1. Global - Created at the Search Service Application in 2010 or SSP in MOSS 2007 2. Local Scope - Created at the SiteCollection Level
