using words like “AND”, “OR” and “NOT”.

Boolean Operators!

Boolean “OR” >>>> allows you to receive more

documents where either or both

keywords appear

Boolean “NOT/“AND NOT“

>>>> retrieving only the first key word you enter

Boolean “AND“ >>>> Narrows it

down by retrieving every key word

you enter

Be specific, whenever possible, use nouns and objects as keywords

Put most important terms first in your keyword list to ensure that they will be searched

Put a +sign in front of each one

Use at least three keywords in your query

Combine keywords, whenever possible, into phrases

Avoid common words, unless they’re part of a phrase

Think about words you’d expect to find in the body of the page and use them as keywords
