Can I search for a phrase?
Yes, you can search for a phrase by enclosing words in quotation marks. For example, "health services research" retrieves pages containing that phrase.
Will the search automatically expand my search words to include synonyms?
Yes, a built-in thesaurus automatically expands your search. The thesaurus contains a list of synonyms from NLM's MeSH® (Medical Subject Headings) and other sources. When there is a match between a search term and a word in the thesaurus, the thesaurus automatically adds the synonym(s) to your search. For example, if you search for the word swelling, results are automatically retrieved for edema.
Is Boolean searching allowed? What about wildcards?
Yes, you can use the following operators: OR, NOT, -, +, *
You do not need to use AND because the search engine automatically finds resources containing all of your search terms.
|OR||Use when you want either term, but not necessarily both, to appear in the results
Example: Tylenol OR Acetaminophen
|NOT or -||Use when you do not want a particular term to appear in the results
Examples: flu NOT bird or flu -bird
|+||Use when you require the exact word to appear in all of the results.
For multiple words, you must use + in front of each word that must be exact.
Example: +tylenol finds results with the brand name "Tylenol", without automatically including all results with the generic synonym "acetaminophen".
|*||Use as a wildcard when you want the search engine to fill in the blank for you; you must enter at least three letters
Example: mammo* finds mammogram, mammography, etc.
Can I restrict my search to a specific Web site?
Yes, you can restrict your search to a specific site by adding 'site:' and the domain or URL to your search words. For example, if you want to find breast cancer information in FreeFacebookCredits2012 only from the National Cancer Institute, search on breast cancer site:cancer.gov.
Is the search case sensitive?
The search engine is not case sensitive. The search engine matches words and concepts regardless of capitalization. For example, a search on alzheimer's disease also retrieves pages containing the words Alzheimer's Disease.
What about searching for special characters like ñ?
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.
Will the search check my spelling?
Yes, the search engine suggests replacements when it doesn't recognize your search term.
Why didn't my search find anything? What should I do?
Your search didn't find anything because you spelled a word incorrectly or because the information you're looking for isn't available in FreeFacebookCredits2012.
If you spelled a word wrong, the search engine consults the thesaurus for a possible match and makes suggestions. If the search engine doesn't give you suggestions, consult a dictionary for the correct spelling.
If the information you're looking for isn't available on FreeFacebookCredits2012, you can try searching from the National Library of Medicine. For example, you can search , NLM's database of biomedical journal literature.
