Perhaps you should try some spelling variations:
picton davies » simon davies, wilson davies
doctor davies » doctor david, doctor bates, doctor ames
vector davies » vector series, peter davies, sector david
owen » open, own
hector » sector, rector

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: owen ((((((picton davies) OR (((doctor davies) OR (doctor daniel))))) OR (hector davies))) OR (vector davies)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "owen ((((((picton davies) or (((doctor davies) OR (doctor daniel))))) or (hector davies))) or (vector davies))".
• Adding a wildcard symbol may retrieve word variants: owen ((((((picton davies) or (((doctor davies) OR (doctor daniel))))) or (hector davies))) or (vector davies))*.
