You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR rank) OR sand) OR (stand OR (hand OR had))) OR (band OR land)) OR ((((((graink OR grain) OR (granttk OR (grantsk OR grandtsk))) OR gran) OR frank) OR (granke OR (graintkt OR grantt))) OR ghana)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand OR rank) or sand) or (stand or (hand or had))) or (band or land)) or ((((((graink or grain) or (granttk or (grantsk or grandtsk))) or gran) or frank) or (granke or (graintkt or grantt))) or ghana)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand OR rank) or sand) or (stand or (hand or had))) or (band or land)) or ((((((graink or grain) or (granttk or (grantsk or grandtsk))) or gran) or frank) or (granke or (graintkt or grantt))) or ghana)) counterinsurgency study ;*.
