Searching for SKU not showing results, Magento 2 EE

Question

Searching with the SKU doesn't return any results. Example of SKU:

ZOR_ZONU3103

I've made sure that the sku attribute is set as Searchable. I have reindexed. I tried SOLR.

Is this a known issue, or something can be adjusted to work somewhere?

Answer 1

I solved this with by upgrading to 2.1 and installing ElasticSearch. I did find some SKU searches were returning results, but not all. Elastic solved all the issues.
