I want to set up a search function at this website, but I will have to learn a bit more about Linux servers first. In the meantime, it is very easy to search through my website (or any website) using Google. On the main Google page, there is a link to "Advanced Search".
Click on this link. Near the bottom of this screen, you will see a box labeled "Search within a site or domain".
Place www.pmean.com in this box. Then fill out the search form above as you normally would.
