Perhaps you should try some spelling variations:
berkeley tanner » berkeley annex, berkeley ann, berkeley chapter
berkeley carter » berkeley chapter, berkeley castle, berkeley late
berkeley unix » berkeley usa
unix lectures » union lectures, six lectures, munich lectures

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: (( ((berkeley tanner) OR (berkeley carter)) lectures ) OR ( berkeley unix lectures )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((berkeley tanner) OR (berkeley carter)) lectures ) or ( berkeley unix lectures ))".
• Adding a wildcard symbol may retrieve word variants: (( ((berkeley tanner) OR (berkeley carter)) lectures ) or ( berkeley unix lectures ))*.
