But still my website is in serchable why?


Although the robots.txt file the standard way to signify to search engines which areas of your sites you would like indexed and which you wouldn't, it doesn't have to be followed.

In the case of the big players, Google, Yahoo, Bing, etc, they do follow the rules.. but some of the smaller players may not and so you may appear in their indexes.

Also, if your robots.txt change is recent a search engine may take time to purge your site from their index.
