• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR grand) OR hard) OR (had OR land)) OR (band OR bonds)) OR ((((((gray OR (migrandts OR graindts)) OR rain) OR irantstd) OR (rawe OR raw)) OR gran) OR (ggaint OR (grant OR (grants OR gbraints))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand OR grand) or hard) or (had or land)) or (band or bonds)) or ((((((gray or (migrandts or graindts)) or rain) or irantstd) or (rawe or raw)) or gran) or (ggaint or (grant or (grants or gbraints))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand OR grand) or hard) or (had or land)) or (band or bonds)) or ((((((gray or (migrandts or graindts)) or rain) or irantstd) or (rawe or raw)) or gran) or (ggaint or (grant or (grants or gbraints))))) counterinsurgency study ;*.
