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: ((((stand OR hard) OR (had OR land)) OR (bank OR bonds)) OR ((((((grand OR rain) OR (irand OR iron)) OR (granddtd OR grawddtd)) OR grawe) OR ((gran OR grant) OR (grain OR gbrain))) OR grow)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((stand or hard) or (had or land)) or (bank or bonds)) or ((((((grand or rain) or (irand or iron)) or (granddtd OR grawddtd)) or grawe) or ((gran or grant) or (grain or gbrain))) or grow)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((stand or hard) or (had or land)) or (bank or bonds)) or ((((((grand or rain) or (irand or iron)) or (granddtd OR grawddtd)) or grawe) or ((gran or grant) or (grain or gbrain))) or grow)) counterinsurgency study ;*.
