Perhaps you should try some spelling variations:
rand » brand, grand
irand » ibrand, igrand, brand, iran, grand
rank » ranks, frank
gffranks » gffrankss, gfffranks
gfffranks » gfffrankss, gffffranks
sand » stand, san
hand » hard
bond » bonds
graind » grained, grain, grains
ggain » gain, grain, again
gran » grant, grain, grand

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 (hand OR band))) OR ((bond OR bank) OR land)) OR (((graind OR (ggain OR main)) OR ((gffranks OR gfffranks) OR (gran OR irand))) OR ((had OR cham) OR ghana))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or rank) or (sand or (hand or band))) or ((bond or bank) or land)) or (((graind or (ggain or main)) or ((gffranks OR gfffranks) or (gran or irand))) or ((had or cham) or ghana))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or rank) or (sand or (hand or band))) or ((bond or bank) or land)) or (((graind or (ggain or main)) or ((gffranks OR gfffranks) or (gran or irand))) or ((had or cham) or ghana))) counterinsurgency study ;*.
