Variable Search Tips

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

    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; there's no need to type in an asterisk. It's also case-insensitive.
