As alas I could not manage to use a PositionFilter right like Jayendra Patil suggested (PositionFilter makes any query a OR boolean query), I used a different approach.

Still with the EdgeNGramFilter, I added the fact that each keyword the user typed in is mandatory, and disabled all phrases.

So if the user ask for "cont info", it transforms to +cont +info. It's a bit more permissive that a true phrase would be, but it managed to do what I want (and doesn't return results with only one term from the two).

The only con against this workaround is that terms can be permutated in the results (so a document with "informatique contrat" will also be found), but it's not that a big deal.
