how d search engines build their indexes and how the indexes are ultimately accessed by the user.

Answer 1

I went to www.google.com and entered how search engines work, and here are the results:
http://www.google.com/search?q=how+search+engines+work&rls=com.microsoft:en-us:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7&rlz=1I7SUNA
The first three or four have the best information.
