This blog post talks of having up to 8 dimensions in the internal k-d tree index. However, the only data type I can find that would use a k-d tree is the 2D geo type. How does one use 3+ dimensions? This would be very beneficial to my use case.

Data type for 3 - 8 dimensions in k-d tree?

You would need to create your own mapping type, which uses the Lucene apis to index such data. Elasticsearch does not expose any types with arbitrary or flexible dimensions.
