I agree with "sweettooth89" and "carlheinz"......if you really want your site to be search-able right away then you have to pay $$$ to big search engin to they index your site really fast.......read up on the link below.

Also, you need to have a file on the root of your web server directory which is called "robots.txt".... robots.txt will allow and disallow certain search engin index your site....all the search engines have web crawler going through the sites and check for robots file...if it's there then the will index the site quicker
Here is sample of robots.txt file
# robots.txt generated by XYZ for
