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.
