NIH Disaster Research Response Program: Help

How to Search

NIH Disaster Research Response Program (DR2), the national framework for research on the medical and public health aspects of disasters and public health emergencies, is a subset of Disaster Lit® : Database for Disaster Medicine and Public Health, a database of the National Library of Medicine (NLM) Disaster Information Management Research Center (DIMRC).

To search DR2, navigate to the Search Page, and type a word or phrase into the search box. Click Search or press Enter. DR2 will look for your search term in these fields:

  • Title
  • Source (name or acronym
  • Date Published
  • Format
  • Annotation
  • URL
  • Publication Type
  • Access Notes
  • Contact information
  • Author
  • Includes Research Tools
  • ID number

Your search terms will be highlighted in the results.

The NIH Disaster Research Response Program (DR2) automatically expands your search to include:

  • Plural, singular, and certain other forms of search words. Example: a search on environment will return results that contain environments, and environmental as well as environment.
  • Words with or without capitalization. Example FEMA is  also searched as fema.
  • Certain synonyms. Example: hurricane will also return results with typhoon or cyclone.

Boolean operators

You can use Boolean operators for greater control over your search:

  • OR retrieves records with either of the search terms, for example flood OR hurricane will retrieve records with flood and records with hurricane
  • AND retrieves records with all the search terms. For example, flood AND hurricane will only retrieve records with both flood and hurricane
  • NOT excludes records containing the specified term, for example public NOT safety finds records containing public but not containing safety
  • Use quotation marks to search for an exact phrase, for example "public health"

For the greatest control over your search, combine parentheses with Boolean operators:

  • (survey OR form) AND "disaster data"
  • ((preparedness OR recovery) AND "natural disaster") NOT hurricane
  • ("epidemic" OR "disease") AND "center for disease control AND prevention"
  • disaster AND (resilience OR coping)
  • "first responder" OR "emergency responder"

To retrieve all records in the database, leave the search box empty, and click Search. The results may take a minute or two to load.

 To perform a new search, click the Clear Search Terms button, which is located to the right of the search box, between the Search and Print/Download buttons.
