grant » grants
grantdtd » grantsdtd, granted
grain » brain, rain

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 hand) OR (had OR land)) OR (band OR (bond OR bonds))) OR (((((grant OR grain) OR grantdtd) OR grace) OR (sand OR (grand OR sand))) OR ((grains OR brains) OR drains))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or rank) or hand) or (had or land)) or (band or (bond or bonds))) or (((((grant or grain) or grantdtd) or grace) or (sand or (grand or sand))) or ((grains OR brains) or drains))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or rank) or hand) or (had or land)) or (band or (bond or bonds))) or (((((grant or grain) or grantdtd) or grace) or (sand or (grand or sand))) or ((grains OR brains) or drains))) counterinsurgency study ;*.
