hand » band
graft » grant, draft, craft
grayk » gray
irantted » granted
graw » grow, raw, draw

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 (hand OR hard)) OR (had OR land)) OR (bond OR bonds)) OR (((((graft OR grayk) OR ((graydtd OR graydtd) OR irantted)) OR graw) OR (gran OR grand)) OR grain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (hand OR hard)) or (had or land)) or (bond or bonds)) or (((((graft or grayk) or ((graydtd or graydtd) or irantted)) or graw) or (gran or grand)) or grain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (hand OR hard)) or (had or land)) or (bond or bonds)) or (((((graft or grayk) or ((graydtd or graydtd) or irantted)) or graw) or (gran or grand)) or grain)) counterinsurgency study ;*.
