Returns all phrases first, then the individual words
Do example with Dogs and Hand signals

17. Boolean Operators And, Or, and Not
Example: all searches related to Intel and AMD processor manufactures
Key in “INTEL AND AMD”
Example 2: all searches not including Intel
Key in microprocessors NOT Intel
Some search sites use + for AND, - for NOT

18. Multiple Sites Don’t be afraid to use other search sites
Give different results
Use more than one

19. Appropriate Keywords
Do not use “the”, “a”, and “in” unless they are part of a phrase
Example: want to find out about bed and breakfasts located in Monticello, Georgia
Key in – Monticello Georgia bed and breakfast
If this doesn’t help – use synonyms
Ex. Hotel or lodging

20. Wildcards A special symbol in conjunction with a part of a word
Ex. Hand sign*
This would find hand signs, hand signals, hand signaling, and any other combination
