Perhaps you should try some spelling variations:
astronomy survives » astronomy survey, astronomy surveys, astronomy studies
moore nautical » moore national, some nautical
board nautical » board practical, board national, board neutral
mile nautical » i nautical, some nautical
ii nautical » i nautical, a nautical, 2 nautical

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: the patrick ((((moore nautical) OR (board nautical))) OR (((mile nautical) OR (((ii nautical) OR (_ nautical)))))) astronomy survives.
• The words AND, OR and NOT may confuse the search; try adding quotes: "the patrick ((((moore nautical) or (board nautical))) or (((mile nautical) or (((ii nautical) OR (_ nautical)))))) astronomy survives".
• Adding a wildcard symbol may retrieve word variants: the patrick ((((moore nautical) or (board nautical))) or (((mile nautical) or (((ii nautical) OR (_ nautical)))))) astronomy survives*.
