• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (bond OR had)) OR ((sand OR (grand OR grant)) OR (gband OR gbank))) OR land) OR (((ghad OR ((ghada OR gada) OR grada)) OR (chandra OR chata)) OR (grants OR migrants))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (bond or had)) or ((sand or (grand or grant)) or (gband or gbank))) or land) or (((ghad or ((ghada OR gada) or grada)) or (chandra or chata)) or (grants or migrants))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (bond or had)) or ((sand or (grand or grant)) or (gband or gbank))) or land) or (((ghad or ((ghada OR gada) or grada)) or (chandra or chata)) or (grants or migrants))) counterinsurgency study ;*.
