You have an option to stop search engine from your webpages how about stop them from CACHING OF YOUR PAGES.
You can stop caching of pages by including this meta tag:
<meta name="robots" content="noarchive">
The Google appliance also uses a small representative piece of each page returned as a search result. You can disable this as well:
<meta name="googlebot" content="nosnippet">
(Note that instructions to the Google crawler can be placed in either robots or googlebot meta tags.) These meta tags must be present in documents at crawl time for the appliance to obey them!
