In Elasticsearch you can define the analyzer for the "_all" field. It is
just configureable through the mapping like any other field.
But you should ask those questions on the Elasticsearch mailing list.

You should ask this on the elasticsearch mailing list.
BTW, look at elasticsearch copy_to feature. Better than _all field.
My 2 cents.
