Hi Team, Hope you are doing well.. We are using elasticsearch mainly for his percolator features , so first we ll index abt 10 lakh queries then we ll throw doc's into that index one by one , then we ll collect return hits . now we successfully connected multiple machines elasticsearch in to one cluster. and each machines have a documents queue and it ll search with ES percolate queries. And my question is , 1, did we need to index percolate queries in all machines or indexing in one machine is enough (becoz of all machines are in same cluster) 2 , if indexing in one machine's is enough then which node it save's that 10L queries .. ?? am assuming that each node have some amount of queries , when search it ll work together. so if one node is down in that cluster , what ll happen to the saved queries in that node ? when we search that time .. is there anyway hits ll reduce ? Thanks in advance.. ---
