hi, i would ask to the expert people, how is possible to hidden own site
from a search that people can do by browser.
till days ago, my site was invisible, but right now
i can see it like first answer by opera.
thank very much.

Most spiders obey /robots.txt so create one saying deny everything to everyone:

User-agent: *
Disallow: /

This most likely will not delete what the spiders have already indexed.
