Perhaps you should try some spelling variations:
resources survey » resources surveys, resource survey, resources series
resources cursed » resource curse, resources used, resources case
learning course » learning curve, training course, learning case
course series » discourse series
wbi learning » 2 learning, 3 learning, 4 learning

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: (( wbi learning ((resources survey) OR (resources cursed)). ) OR ( e learning course series. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( wbi learning ((resources survey) OR (resources cursed)). ) or ( e learning course series. ))~".
• Adding a wildcard symbol may retrieve word variants: (( wbi learning ((resources survey) OR (resources cursed)). ) or ( e learning course series. ))*.
