Searchable Documentation

We have a very extensive documentation on many topics. Sometimes I just want to know if a particular subject is covered in the docs. To facilitate this, could we please add a function to search the docs?

For instance, if I searched for "IPO", I would like to see a list of hits that include this link: https://www.simcountry.com/cgi-bin/cgip?loadDocument&miDocument=sharemarket#initial_public_offering__ipo__3

Is this easy to implement?
