Minus/Negation: What do you call it?
Now you can do searches like this:
lincoln -president
To find pages which mention Lincoln but DON'T have the word president. This is useful for narrowing your search.
It's another way of adding meaning to a word (adding context?).
Lincoln could refer to any number of things -- Abe, memorial, park, town car. The typical way to add context is to enter more search words to more fully describe what you're looking for.
lincoln park
(not to be confused with linkin park)
Using the minus prefix on terms you don't want strips away search results more conservatively. It retains more meanings of the word Lincoln.
Anything not dealing with President Lincoln including park, street, center, cars, etc...:
lincoln -president -abraham -memorial
These are not great examples, but you get the idea.
