ODIN User Guide: Combining Words or Phrases

ODIN God of Wisdom

Go to the:

User Guide Contents

ODIN Online Catalog

 

Next topic:

Limit Search 		   And | Or | Not

And

Use AND to combine words or phrases for a more narrow search. A search using AND will find only items that contain both words. So, the more words you "AND" together, the fewer items you will find. ODIN will automatically "AND" words together, if you don't specify another boolean operator like OR or NOT.

Examples

Enter:
To search for both:  
family relationships and therapy family relationships
therapy
cats and dogs and poetry cats
dogs
poetry

Or

Use OR to combine words or phrases for a broader search. A search using OR will find items that contain either word. So, the more words you "OR" together, the more items you will find.

Examples

Enter:
To search for either:  
theater or drama theater
drama
fbi or federal bureau of investigation FBI
Federal Bureau of Investigation

Not

Use NOT to exclude words or phrases from your search. A search using NOT will find fewer items. So, the more words you "NOT" out of your search, the fewer items you will find.

Examples

Enter:
To search for:  
But not:  
grand forks not county grand forks county
fractals not chaos fractals chaos
