Using the Search function

Advanced search option

With the Advanced Search Option, you can create more complex, sophisticated searches to search.

Advanced Searching is available by selecting the Advanced Search link to the left of the home screen.

 

Search Fields

The searchable fields in the database include: Keyword, Title, Creator and Affiliation. 

Modify your query to narrow your search by making use of the AND, OR and NOT.

Use AND to match documents that contain two or more chosen terms existing anywhere in the text of a single document. This is equivalent to an intersection using sets. The symbol & can be used in place of the word AND.

Use OR to show records that have one or more of the chosen terms.

Use NOT to exclude documents that contain the chosen terms - this is equivalent to a difference using sets.

 

Guideline Example

AND/&

All terms joined by the this operator must be present in the record

health AND substance AND abuse

finds records where all three terms are present in the same field in any order

OR

Any or all of the terms separated by the operator must appear in the record.

medic* OR pharma*

finds records in which either medic* or pharma* is present in the same field in any order

NOT

The term that follows the operator must not be present in the record

(medic* OR health) NOT pharma*

finds records in whic either medic* or heatlh is present but do not include pharma*
