Perhaps you should try some spelling variations:
dimensions session » dimensions vision, extensions session, dimensions impression
control basics » control bisacsh, control asia, control fisico
control basic » control asia, control fisico
control based » control case, content based, context based
session lima » session lxiii, session 2a, session 3a

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: communication ((((control basic) OR (control basics))) OR (control based)) dimensions session lima~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication ((((control basic) OR (control basics))) or (control based)) dimensions session lima~".
• Adding a wildcard symbol may retrieve word variants: communication ((((control basic) OR (control basics))) or (control based)) dimensions session lima*.
