A keyword search will allow the user to
carry out a search that will look for
documents and websites that contain
one or more of the specified words.
7. Wildcards
This search involves the us of a symbols
‘?’ and ‘*’ to replace individual
letters, or sequences of letters.
This is useful when you do not know
how to spell the word.
◦ ? - You can use a question mark to replace a single character.

characters.
Zero characters gives you the option of looking for a character that may or not
be there.
