Search tactics (quick reference)

  • Phrase search for statutory citations and unique contract clauses.
  • Boolean blocks for (A OR B) AND NOT C.
  • Proximity where the platform supports it — co-location of two payment codes, for example.
  • Facets to isolate date ranges and file types before deep reading.
