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 optical astronomy survives") OR ((((("the patrick more practical astronomy survives") OR ("the patrick more positional astronomy survives"))) OR ("the patrick more practical astronomy studies")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"the patrick moore optical astronomy survives\") or (((((\"the patrick more practical astronomy survives\") OR (\"the patrick more positional astronomy survives\"))) or (\"the patrick more practical astronomy studies\"))))".
• Removing quotes may allow a broader search: (( the patrick moore optical astronomy survives ) or ((((( the patrick more practical astronomy survives ) OR ( the patrick more positional astronomy survives ))) or ( the patrick more practical astronomy studies )))).
• Adding a wildcard symbol may retrieve word variants: (("the patrick moore optical astronomy survives") or ((((("the patrick more practical astronomy survives") OR ("the patrick more positional astronomy survives"))) or ("the patrick more practical astronomy studies"))))*.
