Perhaps you should try some spelling variations:
rand » brand, sand
grand » gbrand, gsand, brand
rank » ranks, bank
frank » franks, fbank
ggrankdtd » ggranksdtd, ggbankdtd
hand » hard
band » bank, bond
grawt » graw, graft, grawe
harassed » harnessed, amassed, grassed
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: ((((((rand OR rank) OR grand) OR hand) OR (had OR land)) OR (band OR bonds)) OR (((((grawt OR frank) OR ((ggrankdtd OR gsanddddtd) OR harassed)) OR raw) OR grant) OR (brain OR main))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand OR rank) or grand) or hand) or (had or land)) or (band or bonds)) or (((((grawt or frank) or ((ggrankdtd or gsanddddtd) or harassed)) or raw) or grant) or (brain or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand OR rank) or grand) or hand) or (had or land)) or (band or bonds)) or (((((grawt or frank) or ((ggrankdtd or gsanddddtd) or harassed)) or raw) or grant) or (brain or main))) counterinsurgency study ;*.
