Perhaps you should try some spelling variations:
"preparation du travail" » "preparation _ travail", "preparation a travail", "preparation from travail"
"partition key travail" » "partition k travail", "partition test travail", "partition odes travail", "partition de travail", "partition key travel", "partition le travail"
"partition a travail" » "partition _ travail", "partitioning a travail", "partition au travail", "partition de travail", "partition _ travails"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("preparation du travail") OR ("partition a travail"))) OR ("partition key travail"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"preparation du travail\") OR (\"partition a travail\"))) OR (\"partition key travail\"))".
• Removing quotes may allow a broader search: (((( preparation du travail ) OR ( partition a travail ))) OR ( partition key travail )).
• Adding a wildcard symbol may retrieve word variants: (((("preparation du travail") OR ("partition a travail"))) OR ("partition key travail"))*.
