2. Wildcard & Truncation Symbols
These symbols help you save time and search more efficiently.
They help you to search for all variants of a root word, words with unknown
characters, multiple spellings, and various endings.
Specific symbols and their
functions may vary by database.
See the database Help section to
get the details.
3. Truncation Symbols
go at the end of a root word
will find all endings of that word
Example: pollut*
finds pollute, pollutes, pollution, polluter, polluted,
polluting, pollutant, pollutants
4. Wildcard Symbols
go in the middle of a word
can represent any number of characters
will find variants of that word
Examples: wom?n finds woman, women, womyn
col?or finds color, colour
5. What are Boolean Operators ?
Boolean operators connect and define the relationship between your search terms:
AND
OR
NOT
They can help you save time and search more efficiently.
6. Boolean Operators
AND
is implied in any search string
narrows your search: you find
fewer items, but they're more
specific because they all contain all
the terms
means the search results must
include all terms listed
is the
same as
7. Boolean Operators
OR
finds items containing either term
is good for combining synonyms in a
search
broadens your search: you find
more items, because they only need
to contain one of the terms
8. Boolean Operators
In this example, we use OR to
combine two searches:
teen AND crime = 353,884
+
adolescent AND crime = 307,103
…to get more results on the topic!
10. Searching in specific fields
Most databases will give you the option to search in different fields.
11. Searching in specific fields
The default is usually a full-text search.

12. Searching in specific fields
If your keyword is in the Title or Abstract of the article, it is probably a central concept
in the article, not just mentioned in passing.
So, searching for your keywords in the Title or Abstract field will yield fewer results,
but they will be more relevant.
13. Searching in specific fields
Searching within the Author field will yield articles written by
people with that name.
Note that this yields articles BY Piaget, not ABOUT him.
