You can code this up using some SQL queries and PHP codes to retrieve the contents of your Joomla posts...

or you can use Google's custom search http://www.google.com/cse/

You could integrate Google Search. http://www.google.com/sitesearch/

There are a number of Joomla Site Search Extensions: http://extensions.joomla.org/extensions/search-a-indexing/site-search you could integrate.
