• If you are trying to use Boolean operators, they must be ALL CAPS: ((((san OR (hard OR band)) OR (had OR land)) OR (bank OR bond)) OR ((((grand OR granted) OR (grawe OR (grewe OR gree))) OR (gran OR (graw OR draw))) OR (grain OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((san or (hard or band)) or (had or land)) or (bank or bond)) or ((((grand or granted) or (grawe or (grewe OR gree))) or (gran or (graw or draw))) or (grain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((san or (hard or band)) or (had or land)) or (bank or bond)) or ((((grand or granted) or (grawe or (grewe OR gree))) or (gran or (graw or draw))) or (grain or rain))) counterinsurgency study ;*.
