Conjuctions (aka - Boolean Operators) help broaden or narrow your subject when searching
Searching
Phrases
Use double
quotations marks to search for an exact phrase (search for those words when
they appear together).
Example:
“embryonic stem cell”
Wildcard
and Truncation Symbols enable you to search for variations of words
1. Use ? (a
question mark) to replace each unknown letter from a word. This symbol is
useful if you are unsure of the spelling of a word.
Example: Typing ne?t will retrieve results containing the words next, neat, or nest.
2. Enter the root of a word followed by * (an asterisk) to find all words with the same root. It can be
used to find both the singular and plural forms of a word.
Example: Typing comput* will retrieve results containing the words computer or computing.
Limiters
allow you to narrow the resources you want to search for
Select limiters to narrow your
search. Examples of limiters include:
Remember that the more limiters you choose, the fewer results you will get.
Be sure to type the subject word or phrase in separate fields for the best possible return of articles. Example: Type Autism in one field with And from the drop box and Vaccines in the next field.
Keyword
vs. subject searching
Keyword searches will bring up articles
wherever that word appears in the database (in the articles, subjects, publications,
abstracts, authors, etc.).
