I am endeavoring to comprehend what shard and copy is in Elasticsearch, however I don't figure out how to comprehend it. In the event that I download Elasticsearch and run the content, at that point from what I know I have begun a bunch with a solitary hub. Presently this hub (my PC) have 5 shards (?) and a few imitations (?).
What are they, do I have 5 copies of the record? In the event that so why? I could require some clarification
