• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (far OR had)) OR (band OR (bond OR grand))) OR land) OR ((((gharmt OR (hardt OR harmt)) OR head) OR (((((hardmmo OR hairdmmo) OR harms) OR har) OR (haird OR bcharti)) OR hardmmidm)) OR migrants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (far or had)) or (band or (bond or grand))) or land) or ((((gharmt or (hardt or harmt)) or head) or (((((hardmmo OR hairdmmo) or harms) or har) or (haird or bcharti)) or hardmmidm)) or migrants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (far or had)) or (band or (bond or grand))) or land) or ((((gharmt or (hardt or harmt)) or head) or (((((hardmmo OR hairdmmo) or harms) or har) or (haird or bcharti)) or hardmmidm)) or migrants)) counterinsurgency study ;*.
