Perhaps you should try some spelling variations:
we characterize » well characterized, _ characterized, what characterizes
_ characterize » _ characterizing, _ character, _ characters
petites cites » petites petites, petites pieces, petites ecoles

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 ((we characterize) OR (_ characterize))".
• Adding a wildcard symbol may retrieve word variants: petites cites ((we characterize) OR (_ characterize))*.
