• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((((band OR (hand OR hard)) OR (((ihand OR (grand OR grants)) OR ((grain OR brain) OR rain)) OR ihand)) OR had) OR (rank OR ranks)) OR stand) OR land) OR bond) OR (frank OR (gran OR grant))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((band or (hand OR hard)) or (((ihand or (grand or grants)) or ((grain or brain) or rain)) or ihand)) or had) or (rank or ranks)) or stand) or land) or bond) or (frank or (gran or grant))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((((band or (hand OR hard)) or (((ihand or (grand or grants)) or ((grain or brain) or rain)) or ihand)) or had) or (rank or ranks)) or stand) or land) or bond) or (frank or (gran or grant))) counterinsurgency study ;*.
