Search Tips for ONESearch


What is NICHSR ONESearch

ONESearch is a consolidated search engine that allows you to search NICHSR’s databases and web portals with one search strategy.  ONESearch allows you to search HSRProj (Health Services Research Projects in Progress), HSRR (Health Services and Sciences Research Resources), HSRIC (Health Services Research Information Central) and PHPartners (Partners in Information Access for the Public Health Workforce)

For more information on the contents of each of the above websites, just click on the link to the FAQs, above.

How does the search work?

To search, type a word or phrase into the search box. Click Go, or press the Enter button on your keyboard.
The results for your search are displayed in order of relevance. Every time you search, "All Results" are displayed by default. The results are also categorized into collections: HSRProj,  HSRR, HSRIC, and PHPartners.  If one collection is showing more relevant results, you can limit to that collection by clicking on the limit to the left of the page.

Can I search a phrase?

To search for phrases, type the phrase in quotation marks. For example, type "health services research" in quotes in the search box.

Are Boolean searching and wildcards allowed?

These Boolean operators are available to you: AND, OR, NOT, -, +
The asterisk "*" can be used as a wildcard character.
Note: Using AND is not necessary. All words are searched by default.

Boolean Operator Descriptions




Use 'OR' when you only need at least one of the search words to appear in the results. Example: "HIV OR AIDS"

NOT or -

Use "NOT" or "-" when you do not want a particular term to appear in the results. Examples: "heart defects NOT attack" or "heart defects -attack"


Use "*" as a wildcard to search on all words that contain the letters you enter. You must enter a minimum of three letters plus the "*" character.
Example: "mammo*" would find "mammogram" or "mammography" or "mammoplasty"


Use "+" when you require the exact word to appear in all of the results. For multiple words, you must use put a + sign in front of each word that must be exact. Example: search on "+lipitor cholesterol" if you only want to retrieve results with the brand name "Lipitor" and the word "cholesterol", and no results with the generic synonym "Atorvastatin"

Is the search case-sensitive?

No, the search engine is not case-sensitive. For example, a search on "CAHPS" will also return pages containing "cahps". A search on "AIDS" will also return pages containing "aids".

Will the search check my spelling?

Yes, the search engine checks your search words against all of the words collected from the web site. When a word appears to be misspelled, the search engine looks at all the words it "knows" and offers you a word that could replace it.

What about searching for special characters like ~ or `?

You can use special characters in your search but they're not required. When you use diacritics in your search, the search engine retrieves pages that contain those diacritics. The search engine also retrieves pages that contain the term without special characters. For example, if you search on the word niño, your results include pages that contain the word niño or nino.

What do I do if I get a message saying no results found for the search?

There are a few reasons why you could have received this message:

Your word may be misspelled and the search engine can't find a substitute for it. For example, if you had typed in "dyabeets" when you meant "diabetes", the search engine won't be able to recognize it.

The kind of information you are looking for may not be available from any of the NICHSR databases or web portals.

If you are looking for journal articles, try searching PubMed/MEDLINE at // PubMed/MEDLINE is NLM's bibliographic database of journal article citations and abstracts.

If you are looking for consumer health information, try searching MedlinePlus at // MedlinePlus brings together authoritative information from NLM, the National Institutes of Health (NIH), and other government agencies and health-related organizations.

I limited my search, but want to go back to the original results. What do I do?

Just above your search results, you'll see a box that says "Refinements".  It will display the limit you selected with an "x" next to it.  Just click on the "x" and you'll be taken back to your original search results.
