Perhaps you should try some spelling variations:
"preparation ets travail" » "preparation et travail", "preparation eitan travail", "preparation iveta travail"
"repartition et travail" » "repartition des travail", "repartition du travail", "preparation et travail", "repartition au travail", "repartition et travaux"
"repartition de travail" » "repartition des travail", "repartition du travail", "partition du travail"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("preparation ets travail") or ("repartition et travail"))) or ("repartition de travail"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("preparation ets travail") OR ("repartition et travail"))) OR ("repartition de travail")).
• Removing quotes may allow a broader search: (((( preparation ets travail ) or ( repartition et travail ))) or ( repartition de travail )).
• Adding a wildcard symbol may retrieve word variants: (((("preparation ets travail") or ("repartition et travail"))) or ("repartition de travail"))*.
