You can find that issues mentioned on github.
There's a couple of notes on elasticsearch:
1. In the 6.x branch of ES there is a weird limitation for some fieldtypes, that why dome products cannot be indexed. I opened issue on github about that, but still no answer.
2. It is obviuos, that native TB's (or Prestashop's) search engine can fulfil 90% of customer needs (if not 99) and ES required for shops with huge SKU amounts, that's why there's no much progress in this module development.
