how to make oscommerce search result page url static? like www.nextag.com does, whatever your type a word to search, the site will produce static html url instead of ? included.
Why? A search engine can't run a search queery and should have the returned page in it's index anyways? Why do you need to worry about canonical URLs?
because I search electric kettle on google, I find "www.nextag.com/electric-kettle/search-html" on first page.
