Perhaps you should try some spelling variations:
sand » stand, san, hand
band » bond
grand » brand
harm » farm
harmo » farmo, carmo, haro, jarmo
harms » farms, arms
heat » head
ghartt » gheartt, gchartt, gpartt
hart » heart, chart, part
hartd » heartd, chartd, partd, harth, harto
bharti » bhearti, bcharti, bparti
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 (air OR had)) OR (sand OR ((band OR bank) OR grand))) OR land) OR ((((ghartt OR harm) OR heat) OR ((((harmo OR harms) OR (hard OR hart)) OR (hartd OR bharti)) OR haridm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (sand or ((band OR bank) or grand))) or land) or ((((ghartt or harm) or heat) or ((((harmo or harms) or (hard or hart)) or (hartd or bharti)) or haridm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (sand or ((band OR bank) or grand))) or land) or ((((ghartt or harm) or heat) or ((((harmo or harms) or (hard or hart)) or (hartd or bharti)) or haridm)) or grant)) counterinsurgency study ;*.
