I have made a Elasticsearch setup on a server with configuration - 64 GB RAM and 16 cores. I have created three nodes on this server. One node is both master and data and other two are data nodes. They all are using heap size of 10 GB each.
I have created an index in Elasticsearch which is having documents around 200K . Now when I am using a search query to retrieve all the data from that particular index it is taking around 20-30 seconds which is very huge.
Please suggest me what should I do to reduce this search time.
