Subject: [PATCH] BUGFIX: Remove special characters completely
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

According to https://lucene.apache.org/core/3_4_0/queryparsersyntax.html#Escaping%20Special%20Characters, special characters should be escapeable using a „\“ character. Sadly because of some internal json encoding this doesn’t work properly. Any of these characters break the query.
