• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((rand OR rank) OR (frank OR franks)) OR (hand OR had)) OR land) OR band) OR (((grantd OR ((irand OR irani) OR (igrand OR igrant))) OR (grain OR (raind OR rain))) OR ((gran OR (grand OR grant)) OR grain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand or rank) or (frank or franks)) or (hand OR had)) or land) or band) or (((grantd or ((irand or irani) or (igrand or igrant))) or (grain or (raind or rain))) or ((gran or (grand or grant)) or grain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand or rank) or (frank or franks)) or (hand OR had)) or land) or band) or (((grantd or ((irand or irani) or (igrand or igrant))) or (grain or (raind or rain))) or ((gran or (grand or grant)) or grain))) counterinsurgency study ;*.
