• 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 ((grandtts OR grandes) OR grandets)) OR rain) OR grandttd) OR (grade OR (raw OR draws))) OR gran) OR (geraint OR (grandt OR gsandt)))) 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 ((grandtts OR grandes) or grandets)) or rain) or grandttd) or (grade or (raw or draws))) or gran) or (geraint or (grandt or gsandt)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (band or bond)) or ((((((gray or ((grandtts OR grandes) or grandets)) or rain) or grandttd) or (grade or (raw or draws))) or gran) or (geraint or (grandt or gsandt)))) counterinsurgency study ;*.
