• If you are trying to use Boolean operators, they must be ALL CAPS: ((((grand OR band) OR (had OR land)) OR (bank OR bond)) OR ((((graw OR rawtdtd) OR ((grace OR race) OR rich)) OR gran) OR ((((grayt OR graint) OR brain) OR geraint) OR main))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((grand or band) or (had or land)) or (bank or bond)) or ((((graw or rawtdtd) or ((grace OR race) or rich)) or gran) or ((((grayt or graint) or brain) or geraint) or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grand or band) or (had or land)) or (bank or bond)) or ((((graw or rawtdtd) or ((grace OR race) or rich)) or gran) or ((((grayt or graint) or brain) or geraint) or main))) counterinsurgency study ;*.
