Basically I\'ve got an old static html site ( http://www.brownwatson.co.uk/brochure/page1.html ) I need to add a search box to it to search a folder called /brochure within
A very, very lazy option (to avoid setting up a Google Custom Search Engine) is to make a form that points at Google with a hidden query element that limits the search to your own site:
Aside from the laziness, this method gives you a bit more control over the appearance of the search form, compared to a CSE.
