• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (hand OR hard)) OR (had OR land)) OR (band OR bonds)) OR ((((((gsandt OR grande) OR irank) OR (grandddtd OR ((grandtsed OR graindtsed) OR grants))) OR raw) OR gran) OR (gbrain 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 (band or bonds)) or ((((((gsandt or grande) or irank) or (grandddtd or ((grandtsed or graindtsed) or grants))) or raw) or gran) or (gbrain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (hand OR hard)) or (had or land)) or (band or bonds)) or ((((((gsandt or grande) or irank) or (grandddtd or ((grandtsed or graindtsed) or grants))) or raw) or gran) or (gbrain or rain))) counterinsurgency study ;*.
