Perhaps you should try some spelling variations:
code probabilistic » codes probabilistic, model probabilistic, modem probabilistic
de probabilistic » fe probabilistic, some probabilistic, time probabilistic
dna saint » dna paint, dna saline, pena saint
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)) dna saint-floor".
• Adding a wildcard symbol may retrieve word variants: ecole d'ete ((de probabilistic) OR (code probabilistic)) dna saint-floor*.
