This feature is available on Elastic App Search, but I want to implement this kind of suggestion using Elasticsearch.
I've been messing around this for 3 days straight with no luck. My closest approach to this is to use the completion suggester, by splitting the words in a sentence to form a shingle (manually with nodeJS and some regex & for loops), and then using those shingles as an input in the completion suggester. I am sure there is a better way.
Any idea on how to this better? I'd very much appreciate any pointers you can give
