I have been stuck with an issue with nested mapping for almost 3 days now. Right now I have like 20+ tabs open searching for solutions, finally found a logical explanation and code example from this video. Thanks a lot. I can sleep in peace today!

What is the advantage of nested?
Is it to exclude it from "global" searches (make the search quicker)?
Like for example searching for a post, and excluding all the comments, or reports etc?

Can you provide code samples for each lesson? That would be useful for testing and playing around.

Amita, isn't _type deprecated in 7.1? why is it still being used?

[jeshan]

Very well explained. Can you please make a video for syncing data between MongoDB and Elastic Search in a node js application?

Hi amita, can you explain me how to write query for hierarchy for example
Name: Narayana
Family details:{
Daughter: kalagna,
Son: anirudh
Wife: jayamma
}
Where as daughter kalagna have a daughter and anirudh have a son, so if I search name : narayana, i will get only one result but I am expecting to get the entire family as result. Including daughters family and son family too in the result. Is it possible.? Just like 1 query get the result and again run the query with the result I got.
