Talvez debería tentar con algunhas variantes ortográficas:
"epuration after travail" » "education after travail", "duration after travail", "reoperation after travail", "epuration autre travail"
"preparation a travail" » "preparation _ travail", "preparation au travail", "preparation du travail", "preparation de travail"
"partition a travail" » "partition _ travail", "partitioning a travail", "partition au travail", "partition du travail", "partition de travail"

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: (("preparation a travail") OR ((("partition a travail") OR ("epuration after travail"))))~.
• Removing quotes may allow a broader search: (( preparation a travail ) or ((( partition a travail ) or ( epuration after travail ))))~.
• Adding a wildcard symbol may retrieve word variants: (("preparation a travail") or ((("partition a travail") or ("epuration after travail"))))*.
