Searching Tips

• Searching is not case sensitive unless you use capital letters.
• The search engine ignores quotation marks. The default on the basic search is a word search. If you want to search for a phrase, use the Advanced Search form.
• Boolean searching (using "and," "or," "and not," etc.) is not an option.
• "Data Holdings" refers to ICPSR's metadata records on archived studies. I.e., the study description files.
• Do not use an asterisk (*) to match partial words. The search engine automatically performs "stemming," meaning that partial-word matches will appear in search results.
