Perhaps you should try some spelling variations:
wrox programmer » 10x programmer, non programmer, you programmer
from programmer » from programme, from programming, from programs
knox programmer » non programmer, 10x programmer, you programmer

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: ((((wrox programmer) OR (from programmer))) OR (knox programmer)) to programmer.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wrox programmer) OR (from programmer))) or (knox programmer)) to programmer".
• Adding a wildcard symbol may retrieve word variants: ((((wrox programmer) OR (from programmer))) or (knox programmer)) to programmer*.
