Talvez debería tentar con algunhas variantes ortográficas:
communication conversacion » communication conversation, communication cooperation, communication cohesion
conversacion canonical » conversacion basica, correlation canonical
canonical extensions » radical extensions, central extensions, canonical regression
broad line » broad mite, broad ice
read line » real line, read like, read one

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication conversacion canonical extensions ((((read line) or (read only))) or (broad line))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication conversacion canonical extensions ((((read line) OR (read only))) OR (broad line)).
• Adding a wildcard symbol may retrieve word variants: communication conversacion canonical extensions ((((read line) or (read only))) or (broad line))*.
