No index(Doc) display in the created index pattern

[m-hadi]

Hi
I created an index pattern after creating an index(with some doc)
now I can't see this index (relevant documents) in Discover when I select the index pattern.

more info:
(1- Number of index pattern fields: 254
2- Number of index Doc: 1563
3- I can see the Index Content by : GET /indexname/_search
4- I expanded my time range but It was not useful)

more info:

When you define an index pattern, the indices that match that pattern must exist in Elasticsearch and they must contain data. To check which indices are available, go to Dev Tools > Console and enter GET _cat/ indices . Alternately, use curl -XGET "http://localhost:9200/_cat/ indices "

A simple test would be to follow this tutorial and check results:

Define your index patterns | Kibana Guide [8.11] | Elastic

I checked in the way you said, but there was no problem with the index. The index was available in elastic.

Hi
what field you are using as the time field and can you please show an example of a document?

Thanks

Thank you rashmi
Your guess about the time problem was correct
I try new index pattern without "Time Filter field name: timestamp_ms" . now Index documents were displayed on Discovery.
I don't know why it displays the date 1970, while the date that Twitter gives me is 2020 !?

my twitter date doc without mapping... :

my twitter date doc with my mapping field... :
created_at": {
"type": "date",
"fields": {
"raw": {
"type": "text"
}
},
"format": "EEE MMM dd HH:mm:ss Z YYYY||epoch_millis"
}
