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 ((sand OR hand) OR (hard OR had))) OR (band OR land)) OR (((((grank OR grantk) OR gran) OR frank) OR ((grande OR (ggrandt OR gggrandt)) OR (rankt OR grantkt))) OR ghana)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((rand or ((sand OR hand) or (hard or had))) or (band or land)) or (((((grank or grantk) or gran) or frank) or ((grande or (ggrandt or gggrandt)) or (rankt or grantkt))) or ghana)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((rand or ((sand OR hand) or (hard or had))) or (band or land)) or (((((grank or grantk) or gran) or frank) or ((grande or (ggrandt or gggrandt)) or (rankt or grantkt))) or ghana)) counterinsurgency study ;*.
