Retrieving _timestamp

Elastic Stack Elasticsearch
1

Hi,

I've been facing an issue retrieving _timestamp for one of my indices.
Below is the mapping of my index -

"my_index_1": {
"settings": {
"index": {
"number_of_shards": 4,
"number_of_replicas": 1
},
"aliases": [
"my_index"
]
},
"mappings": {
"my_index_type": {
"_all": {
"enabled": False
},
"_timestamp": {
"enabled": True,
"store": True
},
"properties": {
...
}
}
}
}

I'm using below query to get all documents updated after certain timestamp
(xyz in miliseconds) -
{
"fields": [
"_timestamp",
"_source"
],
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"range": {
"_timestamp": {
"gte": xyz
}
}
}
}
}
}

But this is returning me all the documents in my index including the ones
that are not updated after xyz time and moreover, in the output, I don't
see _timestamp field. Kindly help me with this issue. Also, note that I
cannot change the mapping of my index.

Thanks in advance,
Nishidha

I've got the issue and solution. In above mapping specified, _all > enabled
should be True in order to enable _timestamp and store it.
Hence, closing the post.
