• If you are trying to use Boolean operators, they must be ALL CAPS: (((grand OR (hand OR had)) OR (bank OR land)) OR ((((grawttd OR grade) OR gran) OR (irand OR ((grained OR gained) OR (ggain OR (rain OR brain))))) OR (((grant OR grants) OR irani) OR raw))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((grand or (hand or had)) or (bank or land)) or ((((grawttd or grade) or gran) or (irand or ((grained OR gained) or (ggain or (rain or brain))))) or (((grant or grants) or irani) or raw))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((grand or (hand or had)) or (bank or land)) or ((((grawttd or grade) or gran) or (irand or ((grained OR gained) or (ggain or (rain or brain))))) or (((grant or grants) or irani) or raw))) counterinsurgency study ;*.
