(Research on the Internet)

1. Просмотрите текст и выберите правильный вариант

в следующих предложениях:

1. Google is a keyword/search engine.

2. This WORD is in upper/lower case.

3. AND/WHEN is a logical operator.

Finding information on the World Wide Web needs an Internet

search engine such as Google, Alta Vista or Excite. Search еngines

have a text box where you type in a keyword or words. A search

engine is a software program that reads the keywords in the text box

and searches the Internet for Web pages, websites and other Internet

files that use them. These documents are shown on the computer

screen in a result listing.

When carrying our searches, you should usually be specific and

brief in your choice of words. If the keyword is too general or includes

too many general meanings, the results listing may not be useful.

Different search engines categorize information in different ways,

which changes the way they store and retrieve it.

Using upper case letters in a keyword search will only retrieve

documents that use upper case. Typing in lower case is usually better

because search engines will retrieve documents that use both upper

case and lower case letters.

You can narrow a search using logical operators, such as AND,

OR and NOT. AND retrieves all the words typed in the text box, OR

retrieves either of the words and NOT excludes words. Spelling is

important when typing in keywords, but a search engine will not

usually read punctuation, prepositions and articles.
