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