Perhaps you should try some spelling variations:
astronomy survives » astronomy survey, astronomy surveys, astronomy studies
more positional » more positioning, aware positional, more conditional
pure positional » aware positional, pure conditional, pure rotational
patrick more » patrick moore, patrick moyes, patrick mkie
patrick pure » patrick burke, patrick part, patrick burk

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( the patrick more positional astronomy survives ) OR ( the patrick pure positional astronomy survives ))".
• Adding a wildcard symbol may retrieve word variants: (( the patrick more positional astronomy survives ) OR ( the patrick pure positional astronomy survives ))*.
