The
following operators are accepted - 'and', 'or' and 'not'. Operands must be in lower
case. All words entered are additive unless explicitly told otherwise. For example:
chedder cheese soup = chedder, cheese and soup
(will find every page with all three words on it)
cheddar and cheese not soup
(will find every page with chedder and cheese, but with no soup reference.)
chedder and cheese or soup
(will find every page with chedder and cheese together or just soup)
