• If you are trying to use Boolean operators, they must be ALL CAPS: (((((graint OR gbraint) OR (hand OR hard)) OR (had OR land)) OR (bank OR bond)) OR (((((grawd OR grad) OR grantdtd) OR (grade OR race)) OR gran) OR ((((graint OR gbraint) OR brant) OR geraint) OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((graint OR gbraint) or (hand or hard)) or (had or land)) or (bank or bond)) or (((((grawd or grad) or grantdtd) or (grade or race)) or gran) or ((((graint OR gbraint) or brant) or geraint) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((graint OR gbraint) or (hand or hard)) or (had or land)) or (bank or bond)) or (((((grawd or grad) or grantdtd) or (grade or race)) or gran) or ((((graint OR gbraint) or brant) or geraint) or rain))) counterinsurgency study ;*.
