Perhaps you should try some spelling variations:
"petites pieces _ characterize" » "petites planetes _ characterize"
"petites cites _ characterize" » "petites petites _ characterize", "petites ecoles _ characterize", "petites villes _ characterize"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"petites cites _ characterize\") OR (\"petites pieces _ characterize\"))".
• Removing quotes may allow a broader search: (( petites cites _ characterize ) OR ( petites pieces _ characterize )).
• Adding a wildcard symbol may retrieve word variants: (("petites cites _ characterize") OR ("petites pieces _ characterize"))*.
