I've got the site search function working - but not well enough to implement it yet.
I need to decide how much of a matching page to display. I could chose to display only the matching line(s), I could add in a couple of lines before and after the match, or I could just display the entire page.
Whatever decision I make I'll probably change the 'blog search function to display the same amount on a match.
I should have this ironed out within a few days.
