Perhaps you should try some spelling variations:
practical astronomy » optical astronomy, positional astronomy
patrick moyes » patrick keyes, patrick mayen, patrick mons
patrick more » patrick mark, patrick marx, patrick mons
patrick mkie » patrick mackie, patrick mein, patrick m

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 ((practical astronomy) OR (nautical astronomy)) sergey\") or (\"the ((((patrick more) OR (patrick moyes))) OR (patrick mkie)) ((practical astronomy) OR (nautical astronomy)) sergey\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"the patrick moore ((practical astronomy) or (nautical astronomy)) sergey\\") or (\\"the ((((patrick more) OR (patrick moyes))) or (patrick mkie)) ((practical astronomy) or (nautical astronomy)) sergey\\"))\"".
• Removing quotes may allow a broader search: (( the patrick moore ((practical astronomy) or (nautical astronomy)) sergey ) or ( the ((((patrick more) OR (patrick moyes))) or (patrick mkie)) ((practical astronomy) or (nautical astronomy)) sergey )).
