We have a lot of fields, since we prepend the typeId to the Field in order to avoid the issue with field types overlapping...

How do I do a simple query to get the # of fields in the index?

I don't think there is any API that gives this as a simple number, but you may be able to use the [field stats API](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/search-field-stats.html) to get it.

I cannot figure out how to do it with the field stats.

I can write Java code to do it, so if there is a way to do it with Java that would be awesome.

I am not sure whether it is possible of not, so you may need to retrieve the index mapping and analyse this. As we now do have a limit on the number of fields in an index it would be useful to be able to get this information easily.
