Search Tips for Variables

  • Enter words or strings that are likely to appear in a variable name, label, question, and value labels:

    Presidential election

    will return variables dealing with all presidential elections

    Presidential election Obama

    will return only variables dealing with the 2008 and 2012 presidential elections

  • Use quotes to search for specific phrases:

    "life satisfaction" "minority rights" "community programs"
  • The minus sign may be used to remove certain types of results:

    "Presidential debate" -"Bill Clinton"

    will eliminate the debates from 1992 and 1996 in which Clinton participated.

  • A Boolean "and" is implied in the search.

  • The search automatically does stemming (more info); there's no need to type in an asterisk. It's also case-insensitive.

  • A fielded search is also available.
