Perhaps you should try some spelling variations:
astronomy survives » astronomy survey, astronomy surveys
astronomy studies » astronomy study, economy studies, astronomy status
moore nautical » board nautical, moore national, some nautical
mile nautical » ii nautical, some nautical
i nautical » ii nautical, _ nautical, a 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 (((mile nautical) OR (i nautical)))) ((astronomy survives) OR (astronomy studies)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "the patrick ((moore nautical) or (((mile nautical) or (i nautical)))) ((astronomy survives) OR (astronomy studies))".
• Adding a wildcard symbol may retrieve word variants: the patrick ((moore nautical) or (((mile nautical) or (i nautical)))) ((astronomy survives) OR (astronomy studies))*.
