• If you are trying to use Boolean operators, they must be ALL CAPS: ((((sand OR frank) OR (hand OR band)) OR land) OR (((((grand OR (graint OR grant)) OR ((granted OR grawted) OR grainted)) OR (grants OR (migrants OR migrantts))) OR (gran OR grawt)) OR (gbon OR gbank))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((sand or frank) or (hand or band)) or land) or (((((grand or (graint or grant)) or ((granted OR grawted) or grainted)) or (grants or (migrants or migrantts))) or (gran or grawt)) or (gbon or gbank))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((sand or frank) or (hand or band)) or land) or (((((grand or (graint or grant)) or ((granted OR grawted) or grainted)) or (grants or (migrants or migrantts))) or (gran or grawt)) or (gbon or gbank))) counterinsurgency study ;*.
