A, synchronized to the cluster A from the cluster B
./bin/esm -s http://xxxx:9200 -d http://yyyy:9200 -x src_index -y dst_index -q=site:example.com -w=5 -b=10 -c 10000
Second, the dump A cluster data to a local file
./bin/esm -s http://localhost:9200 -x src_index -m admin:111111 -c 5000 -b -q=site:example.com --refresh -o=dump.bin
Third, import local files to the cluster A
./bin/esm -d http://localhost:9200 -y "dest_index" -n admin:111111 -c 5000 -b 5 --refresh -i=dump.bin
