Hi, David,
Thanks a lot for your prompt help. I got both approaches working, which is
very exciting. I prefer the top_hits aggregation approach. The msearch
approach is not accepting normal JSON payloads, which makes things a bit
harder for processing in Javascript.
My query payload is shown below. Works like a champ!
Best regards,
Jingzhao

]
}
},
