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