ADVANCED SEARCHING ON THE WWW
Автор: Andrew DAWRANT, Vincent BUCK
There are two points you must keep in mind when using a search engine:
- you are only searching through the engines collection of WWW documents and not the World Wide Web itself;
- you can only retrieve WWW documents based on the exact words they contain.
The one thing you need to remember is that search engines are not intelligent agents that categorise websites and pages by publisher, target audience, theme or content. All they do send robots that spider the Web and grind pages to extract the exact words found on them. That information is then compiled in the search engines database in the form of indices.
Thus, when you search with a search engine, your first step should be to try and guess what words are likely to be used in the documents youre looking for. Search engines works with words, not concepts. Unless you choose your words well, the needle in the haystack will most probably not come your way.
