• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (bond OR bonds)) OR (((((grant OR (grank OR grayk)) OR (gbandtd OR granttd)) OR grow) OR (gran OR ((grand OR grayd) OR grawd))) OR grain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (bond or bonds)) or (((((grant or (grank or grayk)) or (gbandtd or granttd)) or grow) or (gran or ((grand OR grayd) or grawd))) or grain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (bond or bonds)) or (((((grant or (grank or grayk)) or (gbandtd or granttd)) or grow) or (gran or ((grand OR grayd) or grawd))) or grain)) counterinsurgency study ;*.
