You might already know how to use a search-engine, but anyway, here's how:
"Search For: Enter your words of interest. Could be "Diving Similan", "Nicolas" etc.
"Criteria:" you can decide, whether you want one of two cases:
If you select AND, the result of the search will be only pages containing ALL your keywords.
If you select OR, the result fo the search will be any page containing at least ONE keyword.
You would usually use AND, otherwise you might end up with too many pages!
"Case:" Well, usually, you would not care, if your keyword was spelled with capitals or small letters. But if you know, that a person you would like to search for is called "Miles", you could select "Case: Sensitive", not to end up with all the pages, where the word is used for a distance.
