Boolean Connectors (and, or, not)

CONNECTORS: AND

• AND narrows a search. Use it in the "Search " box. For example:
  computers and space

  

  The dark grey area represents records containing both terms. The search would find records such as:

  • Computers weave materials for the space age ...
  • Apples in space ...
  • Apple II computers and space travel ...
• NOTE: Do not substitute an ampersand (&) for the word "and."

CONNECTORS: OR

• OR broadens a search. Use it in the "Search" box. For example:
  lemons or oranges

  

  The dark grey area represents records containing either term or both terms. The search would find records such as:

  • Bitter lemons.
  • Wild oranges.
  • Oranges & lemons.
• NOTE: When using the OR connector in conjunction with the AND or NOT connectors, parentheses should be used to "group" search terms to ensure correct search results. For example, a search for: parents and daughters or sons might retrieve items about "sons" without any reference to "parents." However, a search for: parents and (daughters or sons) would retrieve only items on "parents and daughters," "parents and sons," or "parents and both sons and daughters."

CONNECTORS: NOT

• NOT eliminates terms from a search. Use it in the "Search" box. For example:
  stocks not bonds

  

  The dark grey area represents records without the second term. The search would find records such as:

  • When to sell stocks.

  but not:

  • How to buy foreign stocks and bonds.

  ... therefore, use NOT with caution!
