Search Tips

• Use the operators AND, OR, or NOT between terms. Use upper or lowercase.
  Type AND between each term to find both (or all) of the words.
           Example: data AND geograph* (the * is a wildcard)
  Type OR between each term to find either term.
           Example: labor OR work
  Type NOT between terms to find the first, but not the second term.
           Example: resource NOT "natural resource" (use NOT with caution)

• Adjacent terms (or terms placed in quotes) are searched as a phrase.
          Example: foreign investment (or try "foreign investment")

• Wildcards: Asterisk (*) finds zero or more characters. Question mark (?) finds one character. Wildcards may be used anywhere in the word.
          Example: geograph* finds geography, geographies, geographic, etc.
          Example: dat? finds data or date, but not datum, datasets, dates, etc.
          Example: cent?? finds center or centre, but not centers or centres
  

• Use parentheses around related concepts to clarify your search.
          Example: infectious disease and environmental conditions
          Example: household* and (age or sex)
          Example: (input or investment) not "stocks"

Additional Notes

• The search reads operators from left to right.
• The AND operator takes precedence over the OR operator.
• Terms enclosed in parentheses are evaluated first; innermost parentheses are evaluated first when there are nested parentheses.
• To search for the actual words AND, OR, or NOT, enclose the term in double quotation marks.
          Example: housing "and" construction (also try "housing and construction")
