I have seen here https://github.com/elastic/elasticsearch/issues/22923 that the
include_in_all parameter will no longer be available in ES 6.0 as the
_all field will also stop to be created.
I use it a lot in my app because on one hand, I don't want some "technical" hidden fields that I don't want to be indexed when a user search for a value (using
match_all) but on the other hand, I do want to be able to perform a query on this field.
What will be configurable in the mapping to solve this problem ?
