Dreamweaver MX Search Engine

Help in creating a master/results site search engine using MS Access with a keywords column.

I would like a tutorial on how to create a site search engine using multiple words in a text box using an MS Access database with a column called keywords. I am curious if it is better to use commas after each submitted word (i.e. cat, dog, black, white) and how to be able to search using multiple words and, if possible, have the results based on number of words matched.
