What's the difference between the two deprecation warnings on the [Boolean Type](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/boolean.html) page? It seems like they are both saying to just use "true" and "false".

Also, is Boolean fully supported with search now? I seem to remember that it wasn't pre-v2.0.
