Boolean Search

Boolean Search Options

Supported boolean search operators when in boolean mode are:

  • AND
  • OR
  • NOT
  • NEAR (unordered proximity search)
  • ONEAR (ordered proximity search)

Examples:

  • great AND expectations finds records with keyword "great" and keyword "expectations"
  • great OR expectations finds records with keyword "great" or keyword "expectations"
  • great NOT expectations find records with keyword "great" that do not have keyword "expectations"
  • great NEAR/2 expectations finds records with keyword "great" and keyword "expectations" within two words, in any order
  • great ONEAR/2 expectations finds records with keyword "great" and keyword "expectations" within two words after "great"

Combining booleans and specifying search fields:

  • Subject:"King, Stephen" AND NOT Author:"King, Stephen" finds works about Stephen King where he is not the author
  • Author:"King, Stephen" AND (Language:(French OR Italian)) finds work by Stephen King in French or Italian
  • Format:DVD AND Subject:"Shakespeare, William" finds DVDs where William Shakespeare is one of the subjects

Other notes on the boolean search:

  • Capitalization matters for search field names--use Author, not author
  • Double quotes can be used to indicate a phrase, e.g. "King, Stephen"
  • Once you have performed a boolean search you can refine your results using the search facets
