This document discusses advanced search tools for databases including wildcard and truncation symbols to search for word variants, Boolean operators like AND, OR and NOT to connect search terms, and searching specific fields like title, abstract, or author to focus searches. Wildcard and truncation symbols can represent unknown characters or word endings to broaden searches, while Boolean operators can narrow searches by requiring all terms or broaden searches by allowing either term. Searching specific fields yields fewer but more relevant results focused on that field.

1. Advanced Search Tools
 Truncation & Wildcard Symbols
 Boolean Operators
 Searching in Specific Fields

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

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!

9. Boolean Operators
NOT
 eliminates hits containing a certain
keyword
 narrows your search
 removes unwanted topics from your
results

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.
is the
same as

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.
