I get an error when I search "l'exode" in the field "tous les mots suivants".
Just before I tried a search on "exode" and didn't get an error.

It's an error in the query parser: QueryModel escapes quotes by doubling them whereas the parser expects a backslash.
According to JSR 170 p 310, it seems that QM is right, but fixing is easier in QueryModel (because it's not in core)

Also, the exception isn't properly catched.

about double quotes: in this case, this is a Lucene special character (see http://lucene.apache.org/java/docs/queryparsersyntax.html)
we want escaping of those to be configurable, because it depends on applicative use-cases.

The default application will escape double quotes, thus leaving ~, ^ to play with.

There is now a registrable escaper. By default, this is LuceneMinimalEscaper, that takes care of double quotes only.
