A means of searching for links from one location to another typically within
websites. (e.g. Generate a site map.) In Vista, this is a function of the
Search Index verifying that the nodes within the search index (database)
actually lead to something and perform necessary updates to the index.

Search engine may create a map that uses the alphabet as nodes (forks in
So, on the first rung you have 26 nodes indicating the first letter
starting any word. (These are the "start pages".)
On the next rung, each letter has 26 more nodes indicating the second
You would find the word "at" on the second rung with a pointer branching
from the "at" node to the location on the hard drive where the word is
located in a file. (There may be several locations associated with this node
since "at" is a fairly common word.)
Unused nodes are simply removed to speed up the search when requested.
Crawling is an automated process that walks along the path from node to
node verifying that something exists at each location indicated by the index
to keep it up-to-date and efficient.
