How to add a site search in HTML?

[Henry Smith]

There is no feature in HTML that will perform the search. But you do have 3 alternative options:

1) You can integrate 3rd-party search engines like Google into your site. (Or see one of these examples.)
2) You can upload a CGI page which uses PHP, Perl, or another scripting language to perform the local search for you.
3) Lastly, there are some options for JavaScript search engines which work right inside the page.
