Perhaps you should try some spelling variations:
les rapports » ses rapports
recherche du » recherche sur, recherche et, recherche und
recherche de » recherche sur
rapports » rapparts, rapport
ports » parts, port
transports » transparts, transport

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: ((((les rapports) OR (les ports))) OR (((les transports) OR (des transports)))) de ((recherche du) OR (recherche de)) fit.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((les rapports) or (les ports))) or (((les transports) or (des transports)))) de ((recherche du) OR (recherche de)) fit".
• Adding a wildcard symbol may retrieve word variants: ((((les rapports) or (les ports))) or (((les transports) or (des transports)))) de ((recherche du) OR (recherche de)) fit*.
