frank » franks
rank » ranks
grant » grants
ghard » hard, guard, gharo
haro » hard, harm, hart
gheat » great, wheat, cheat, ghead

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 (sand OR stand)) OR (bank OR had)) OR land) OR bond) OR (((frank OR rank) OR grant) OR (ghard OR ((haro OR ((gheat OR heat) OR (heart OR part))) OR (hari OR charts))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or (sand or stand)) or (bank or had)) or land) or bond) or (((frank or rank) or grant) or (ghard or ((haro or ((gheat OR heat) or (heart or part))) or (hari or charts))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or (sand or stand)) or (bank or had)) or land) or bond) or (((frank or rank) or grant) or (ghard or ((haro or ((gheat OR heat) or (heart or part))) or (hari or charts))))) counterinsurgency study ;*.
