• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR (rank OR frank)) OR hand) OR (had OR land)) OR (bond OR bonds)) OR ((((((gsand OR irand) OR band) OR granktd) OR (grow OR raw)) OR gran) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or (rank OR frank)) or hand) or (had or land)) or (bond or bonds)) or ((((((gsand or irand) or band) or granktd) or (grow or raw)) or gran) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or (rank OR frank)) or hand) or (had or land)) or (bond or bonds)) or ((((((gsand or irand) or band) or granktd) or (grow or raw)) or gran) or graint)) counterinsurgency study ;*.
