Perhaps you should try some spelling variations:
astronomy survives » astronomy survey, astronomy surveys, astronomy studies
moore nautical » board nautical, mile nautical, moore national
some nautical » some analytical, some critical, some natural
ii nautical » i nautical, _ nautical, a nautical
practical » practice

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