• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((((rand or ((((ghandttd or gghandttd) or gghandttd) or granttd) or (ihand or irani))) or had) or ((rank OR frank) or fbanks)) or sand) or land) or band) or (trans or (gran or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((((rand or ((((ghandttd or gghandttd) or gghandttd) or granttd) or (ihand or irani))) or had) or ((rank OR frank) or fbanks)) or sand) or land) or band) or (trans or (gran or main))) counterinsurgency study ;*.
