Power Searching Options
Boolean operators allow terms to be combined with logic operators. The following operators are allowed: AND, OR, and NOT. Note: Boolean operators must be ALL CAPS
The AND operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the AND operator is used. The AND operator matches records where both terms exist anywhere in the field of a record.To search for records that contain "economics" and "Friedman" use the query: economics Friedman or economics AND Friedman
The OR operator links two terms and finds a matching record if either of the terms exist in a record.To search for records that contain either Keynes or Friedman, use the query:Keynes OR Friedman
The NOT operator excludes records that contain the term after NOT.To search for records that contain "economics" but not "Friedman" use the query:economics NOT Friedman
Note: The NOT operator must be combined with other terms. For example, the following search will return no results:NOT economics
The Library Catalog does not search for phrases unless they are entered in quotes, such as “Chicago School”.
A phrase entered without quotes will be searched as a Boolean “AND”: Chicago School will be searched as Chicago AND School. This may not be apparent due to the relevance ranking of your results.
By default, searches in the Library Catalog make use of stemming. This means that, in addition to searching for your search terms as entered, the Catalog will also search for related terms, such as plurals, participles, and adjectives with the same root. For example, a Title search for “politic” will also return records that include “politics”, “political”, and “politically”.
Stemming is not applied to Author, Call Number, or ISBN, ISSN, etc. keyword searches.
Search without stemming by entering one the following field labels in the keyword field. Separate the field label and your term with a colon and no spaces.
|title_full_unstemmed||Searches the main title index||title_full_unstemmed:politic finds politic but not politics or political|
|topic_unstemmed||Searches subject headings||topic_unstemmed:rhodes finds Isle of Rhodes but not Rhode Island|
|allfields_unstemmed||Searches all fields but call number||allfields_unstemmed:concept finds concept, but not concepts or conceptual|
Use the tilde ~ symbol at the end of a Multiple word Term. For example, to search for economics and Friedman that are within 10 words of each other, enter:
The quotation marks are required.
Term boosting allows you to give a search term more weight in the relevance ranking. Use the ^ symbol followed by a number
economics and Friedman^5
Truncation and Wildcards
Use the asterisk symbol to search for variations of words.
Searching for test* will find test, tests, tester, testing, etc.
Use the question mark symbol to replace one character in a word.
For example, to search for "text" or "test" you can use the search:
Use the asterisk symbol to replace multiple characters in a word
Searching for colo*r finds color and colour.
Truncation and wildcards cannot be used in phrase searches.
You can limit a search to specific fields in a record by entering field names in the keyword search box, using the syntax: field_label:search terms.
Some general guidelines for using field searching:
- You must not leave spaces between the field name, the colon and your search terms.
- Field names are case-sensitive.
- Multiple fields may be combined using Boolean operators.
- Enter phrases in quotes.
- To search for multiple terms in a field, enclose them in parentheses. This will combine the terms using the Boolean AND operator.
- Authors must be entered as "Last Name First Name". A comma is not necessary.
