• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (hand OR hard)) OR (had OR land)) OR (bank OR bonds)) OR ((((iband OR ggraindtd) OR (drawe OR (graw OR grow))) OR ((gran OR gsand) OR ((grant OR (migrants OR migrands)) OR grandt))) OR rain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (hand or hard)) or (had or land)) or (bank or bonds)) or ((((iband or ggraindtd) or (drawe or (graw OR grow))) or ((gran or gsand) or ((grant or (migrants or migrands)) or grandt))) or rain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (hand or hard)) or (had or land)) or (bank or bonds)) or ((((iband or ggraindtd) or (drawe or (graw OR grow))) or ((gran or gsand) or ((grant or (migrants or migrands)) or grandt))) or rain)) counterinsurgency study ;*.
