Perhaps you should try some spelling variations:
philip hohn » philipp hohn, philip john, philip hoby
philip hunt » philip hans, philip henry
philip hen » philip henry, philip hans, philip h
biochemist » biochemists, biochemistry, biochemie

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: ((((philip hen) OR (philip hohn))) OR (philip hunt)) (british biochemist).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((philip hen) OR (philip hohn))) or (philip hunt)) (british biochemist)".
• Adding a wildcard symbol may retrieve word variants: ((((philip hen) OR (philip hohn))) or (philip hunt)) (british biochemist)*.
