Query a multi level nested document at different levels - elasticsearch

Question

I have data in the following format
{
"mappings": {
"blog": {
"properties": {
"comments": {
"type": "nested",
"properties": {
"subComments": {
"type": "nested"
}
}
}
}
}
}
}
And i have multiple documents with data like
{
"blog_post_id": "blog1",
"comments": [
{
"id": "c1",
"user_id": "u1",
"timestamp": 1487781975676,
"value": "CVLA1",
"subComments": [
{
"value": "sub comment 1"
},
{
"value": "sub comment 2"
}
]
},
{
"id": "c2",
"user_id": "u1",
"timestamp": 1487781975686,
"value": "CVLA2",
"subComments": [
{
"value": "sub comment 3"
},
{
"value": "sub comment 4"
}
]
}
]
}
I'd like match the blog documents which have comment value CVLA1 and a suc comment which has value "sub comment 2".
I wrote a query like
{
"query": {
"nested": {
"path": "comments",
"query": {
"bool": {
"must": [
{
"match": {
"comments.value": "CVLA1"
}
},
{
"nested": {
"path": "comments.subComments",
"query": {
"match": {
"commnets.subComments.value": "sub comment 2"
}
}
}
}
]
}
}
}
}
}
But this one doesn't work as expected. Any help how to query at different levels of a multi level nested document.

Answer 1

You have a typo in your query around commnets.subComments.value. It should be comments.subComments.value. So the entire query would look like this:
{
"query": {
"nested": {
"path": "comments",
"query": {
"bool": {
"must": [
{
"match": {
"comments.value": "CVLA1"
}
},
{
"nested": {
"path": "comments.subComments",
"query": {
"match": {
"comments.subComments.value": "sub comment 2"
}
}
}
}
]
}
}
}
}
}
I double checked - it works fine for me.
