• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (band OR bond)) OR ((((((gray OR (grantors OR irants)) OR rain) OR grantstd) OR (draw OR graw)) OR gran) OR (geraint OR (grant OR (grants OR (graints OR grains)))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (band or bond)) or ((((((gray or (grantors or irants)) or rain) or grantstd) or (draw or graw)) or gran) or (geraint or (grant or (grants or (graints OR grains)))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (band or bond)) or ((((((gray or (grantors or irants)) or rain) or grantstd) or (draw or graw)) or gran) or (geraint or (grant or (grants or (graints OR grains)))))) counterinsurgency study ;*.
