specific deep » specific sleep, specific dea, specific death
pacific deep » pacific area, pacific acp
2000 pacific » 2009 pacific, 2001 pacific, 2002 pacific
pacific some » pacific slope, pacific south, pacific sea

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: (( 2002 ((pacific caves) OR (pacific lives)) ) OR ((( 2009 ((pacific deep) OR (specific deep)) ) OR ( 2000 pacific some )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 2002 ((pacific caves) or (pacific lives)) ) or ((( 2009 ((pacific deep) OR (specific deep)) ) or ( 2000 pacific some ))))".
• Adding a wildcard symbol may retrieve word variants: (( 2002 ((pacific caves) or (pacific lives)) ) or ((( 2009 ((pacific deep) OR (specific deep)) ) or ( 2000 pacific some ))))*.
