Preferences In Searching Posts From Search Engines

I got a question from my organization yesterday. Is it possible for me to restrict my posts appearing on google search (i mean on different search engines)? It's fine people logging into progresstalk and searching but not from search engines.

I don't see any option but just wanted to check if anyone is aware of such stuffs.

There's no option for that, at least any option that is available to users. If you post here then Google will index it.
