Perhaps you should try some spelling variations:
teaching learning » machine learning
transport bei » transport b, transport based, transport below
learning case » learning based, learning curve, learning chapter
transport de » transport der, transport des, transport du
new teaching » does teaching, 1 teaching, 10 teaching
f new » _ new, a new, 3 new

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( luis _ bus ((transport bei) OR (transport de)) marx ) or ( luis f new teaching learning case ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis _ bus ((transport bei) OR (transport de)) marx ) OR ( luis f new teaching learning case ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis _ bus ((transport bei) OR (transport de)) marx ) or ( luis f new teaching learning case ))*".
