First, I am new to Elasticsearch. I am trying to use regex search feature. It is working ok, except for the special chars. Ok I already have read on several places "If you are using the default analyzer, that's expected".  
My question is how to make a property not analyzed then ? I could not find a working example. I use elasticsearch v5.5.0. Can you provide me with an example of the mapping where only one property of a document is not analyzed please? Thanks in advance.

Map the field as a [keyword datatype](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/keyword.html).
