Is there a feature in ES where when i give a document to elasticSearch , it
tells me which all documents in the ES are similar to the document i
Like instance let there be a score for similarity checking between documents
(between 1 to 100).
Whenever i add a document to ES , it should tell me which all documents have
similarity of score more than 70.
Also i want ES to look into similarity of last N days only (Not the whole
lot if it takes too much of processing power).
