Perhaps you should try some spelling variations:
code probabilistic » codes probabilistic, model probabilistic, modem probabilistic
de probabilistic » fe probabilistic, some probabilistic, time probabilistic
data saint » data paint, data sasmint, data saving
d'ete » d'este, d'etre

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: "ecole d'ete ((de probabilistic) OR (code probabilistic)) data saint-floor".
• Adding a wildcard symbol may retrieve word variants: ecole d'ete ((de probabilistic) OR (code probabilistic)) data saint-floor*.
