Search Feature for Dynamic data website

I want to add a search feature for a website I’m building. I would like to be able to search for through multiple tables for things like usernames, film titles, film descriptions, ect. However, all of the content is stored in a mysql database and generated dynamically with php. How can I add a search feature under these conditions?

Take a look at Google Adsense, they have ready made search boxes which are quite easy to add to a site and give Google an insentive to frequently crawl the site.

But there is nothing to crawl. As I said before: I would like to be able to search for through multiple tables for things like usernames, film titles, film descriptions, ect. However, all of the content is stored in a mysql database and generated dynamically with php. How can I add a search feature under these conditions?

Google will build a set of search results on the page submissions they receive.

If your require help in generating forms and queries then ask the Mod to move this thread to either “PHP” or “Databases & MySQL” section.
