Title: Don't tokenize boolean fields in ElasticSearch

You can't tokenize a boolean field in ElasticSearch and it will refuse to accept produced schema.
This will in effect result in automatic creation of mapping in ES which will ignore indexed/stored settings and make it impossible to sort on a text field.
