NOT Operator
public execution NOT mcveigh
  • Excludes records that contain the term following
    NOT.
  • Can eliminate false hits.
  • Use with caution.

mcveigh
public execution

Field Searching
  • Instead of looking for your terms ANYWHERE within
    the record, look for them in specific fields.
  • Title and Subject fields are often the most
    effective for narrowing a search to the most
    relevant articles.

Dont forget about Nesting
  • ANY time you combine the AND operator and the
    OR operator in a search, you MUST use
    parentheses to indicate the relationships you
    want among the terms.
  • e.g.
  • execution and (witness or public)
