Perhaps you should try some spelling variations:
far » farm
sand » stand, san, hand
band » bank
grand » brand
harm » farm, hairm, hartm, harim
head » lead
heari » heart, heard, henri
ghartt » ghairtt, gharttt, gharitt
har » hair, hart, hari
hard » haird, hartd, harid
bharti » bhairti, bhartti, bhariti
hartidm » hairtidm, harttidm, haritidm
grant » grants

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: ((((bonds OR (far OR had)) OR (sand OR ((band OR bond) OR grand))) OR land) OR ((((ghartt OR harm) OR (heat OR head)) OR ((((heari OR haiti) OR har) OR (hard OR bharti)) OR hartidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (far or had)) or (sand or ((band or bond) or grand))) or land) or ((((ghartt or harm) or (heat OR head)) or ((((heari or haiti) or har) or (hard or bharti)) or hartidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (far or had)) or (sand or ((band or bond) or grand))) or land) or ((((ghartt or harm) or (heat OR head)) or ((((heari or haiti) or har) or (hard or bharti)) or hartidm)) or grant)) counterinsurgency study ;*.
