I have place the same question in the kibana section but after searching more deeply I suppose that is a problem whit the DB.
(like this old thread for example : https://discuss.elastic.co/t/problem-with-single-quote-mark-in-json/3734/3b )
I must search the character ' (single quote) from a string (only the single quote) but when I try so search it I don't receive any response, it's like I place an empty query.
Also I don't receive sort of error back...
I have already try to use the UTF-8 code and a regex... No match and also no error.
Any suggestion? Is it possible or not?
