Advanced Searching in Westlaw/Lexis/Bloomberg

Basic Types of Advanced Searching Tools:

  • Boolean Logic (AND, OR, NOT) - Used to improve precision and increase relevancy by ensuring sources include (or exclude) relevant terms.
  • Phrase Searching (i.e., "domestic violence") - Used to exclude sources that do not include these terms in this specific order.
  • Proximity indicators (i.e, /s, /p, /5) - Used to improve precision and increase relevancy by ensuring sources include your relevant terms near each other.
  • Truncators (i.e, crim!) - Used to catch plural and/or adjective forms of a particular term.
  • Segment searching (i.e, HE, DA, OP, etc.) - Used to exclude sources that do not include a particular term within a segment of a document.
