Index pages with "Fetch content from another content item"

I'm thinking of setting up a site that has the same content under multiple subfolders, and when a search is made, only search in that subfolder and on thoose pages, kind of like this:

• Startpage
  • Original page 1
  • Original page 2
  • Subfolder 1
    • Page with fetched content 1 (from Original page 1)
    • Page with fetched content 2 (from Original page 2)
  • Subfolder 2
    
    • Page with fetched content 1 (from Original page 1)
    • Page with fetched content 2 (from Original page 2)

When the visitor is performing a search in "Subfolder" I wan't to the result to be "Page with fetched content 1 or 2" not the "Original page 1 or 2".

Is this possible or will Find only index the "Original page 1" and "Original page 2"?
