• If you are trying to use Boolean operators, they must be ALL CAPS: (((rand OR (grand OR gsand)) OR land) OR ((((bank OR (ghad OR (ghada OR ((handa OR (hanna OR anna)) OR harda)))) OR ghana) OR (hand OR had)) OR grants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((rand or (grand or gsand)) or land) or ((((bank or (ghad or (ghada or ((handa or (hanna or anna)) or harda)))) or ghana) or (hand OR had)) or grants)) counterinsurgency study ;~".
