Walk through the directory structure, looking for files that match the name you input, or that contain data that matches. You can use the grep command (Unix/Linux) to do that. In fact, Linux and Unix have a very neat command line tool called "find" that can handle that very well. I use it for such purposes all the time.

Search engines use automated software programs knows as spiders or bots to survey the Web and build their databases. Web documents are retrieved by these programs and analyzed.
