the part of the url after the hash/pound sign (#) is a fragment identifier. google will only index complete documents. i.e. to a user-agent http://example.com/category/product#partwaydown is the same document request as http://example.com/category/product#halfwaydown and the "partwaydown/halfwaydown" meaning is user-agent dependent. in some cases if your page navigation is well-constructed google will use the links to document fragments as indented "jump to ..." links in the search results.
