Understanding Cobalt search

Hi!

Example:

Section1 - Type1

-- field name: "Title"

-- field name: "Company"

Section2 - Type2

-- field name: "Title"

-- field name: "Company"

So it's 2 different sections, 2 different types, but the field names are equal

1 - When using simple(text box) or advanced search, Cobalt will retrieve search results from both sections or the current section ?

I believe Cobalt has multi-type search, and not a multi-section search correct?
