Searching with Key Words and Boolean
Operators: Example 1: How are pesticides affecting the air in San Joaquin Valley? Key words: pesticides air San Joaquin Valley Example 2: Are invasive plants a problem in California? Key words: invasive plants California Phrase
Searching Examples: "San Joaquin Valley" "Central Valley" "invasive plants" Truncation Boolean Operators Keyword searching uses Boolean Operators to link the search terms together. The Boolean operator you will use most often is AND. The Boolean Operator AND
means that the terms connected by it must be in the search results. In
Example 1 the keywords were pesticides and
air and San Joaquin Valley, so my search
query would be pesticide* and air and "San Joaquin Valley" OR is another Boolean Operator. It is used when you have two words that mean the same thing or are very similar in meaning, and you want to find all the articles regardless of which term is used. Examples:
"San Joaquin Valley" OR "Central Valley" Examples: air and (pesticides or insecticides) and ("San Joaquin Valley" OR "Central Valley")
