Perhaps you should try some spelling variations:
de probabilistic » code probabilistic, some probabilistic, time probabilistic
fe probabilistic » free probabilistic, fire probabilistic, life 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 (fe probabilistic)) data saint-floor".
• Adding a wildcard symbol may retrieve word variants: ecole d'ete ((de probabilistic) OR (fe probabilistic)) data saint-floor*.
