http://pharmainfo.net/TiX_Archives+main.html

The first thing I'd do is make sure there's a link to the page from
the home page of the site and/or from other legitimate pages already
indexed by Google.

link is there with the word more>>. do i have to rename the word
something like search word?

You could try placing robots.txt file under root directory of your
webserver. As far as I can tell you don't have one there yet.

You could find information about Search Robot Crawling and Indexing at
http://www.searchtools.com/robots/robot-checklist.html .  Let me know
if you need any help designing the file.
