• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((((rand OR ((grand OR grayd) OR graw)) OR (((grayt OR grandt) OR grain) OR (igsand OR iron))) OR hand) OR (rank OR bank)) OR san) OR land) OR band) OR (trans OR (gran OR irant))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((rand or ((grand OR grayd) or graw)) or (((grayt or grandt) or grain) or (igsand or iron))) or hand) or (rank or bank)) or san) or land) or band) or (trans or (gran or irant))) counterinsurgency study ;~".
