Use Boolean operators "AND'', "OR'', and "NOT".
For example searching for:
mouse and computer
will return only those documents regarding the kind of
mice attached to a computer and not the rodents.
Searching for:
cat or kitten or feline
will return only those documents regarding cats.
Searching for:
mouse or mice and not computer
will return only those documents regarding mice (the
rodents) and not the kind attached to a computer.
Searching for:
mouse AND computer OR keyboard
is the same as searching for:
(mouse and computer) or keyboard
in that they will both return only those documents regarding
either mice attached to a computer or any kind of keyboard.
