Query-handling – The Google Way
Google has a very simple 3-step procedure in handling a query submitted in its search
box.
1. When the query is submitted and the enter key is pressed, the web server
sends the query to the index servers. Index server is exactly what its name
suggests; it consists of an index much like the index of a book which displays
where is the particular page containing the queried term is located in the entire
book.
2. After this, the query proceeds to the doc servers, and these servers actually
retrieve the stored documents. Page descriptions or “snippets” are then
generated to suitably describe each search result.
3. These results are then returned to the user in less than a second!
