It is important to notice that you should not have a space between the minus sign and the term. In
effect, if you search for [salsa - dancing] with that space there, you are just saying [salsa dancing]. You
are now starting to emphasize that term which is probably not what you meant. Keep the minus sign
touching the term you are trying exclude and you will get the effect you want.
Effective: [salsa -dancing]
Ineffective: [salsa - dancing]
