range query not working as intended [elasticsearch] - elasticsearch

Question

I am executing a simple range query. But I see that an empty result being returned. But I know that they are many records/documents that satisfy the query.
Below are the 3 types of queries I have tried.
(the third one is intended query)
1)
"query": {
"range" : {
"endTime" : {
"gte" : 1559076400.0
}
}
}
2)
"query": {
"bool": {
"must": [
{"range" : {
"endTime" : {
"gte" : 1559076401.0
}
}
}
]
}
}
3)
"query": {
"bool": {
"filter": [
{"range" : {
"startTime" : {
"gt" : 1356873300.0
}
}
},
{"range" : {
"endTime" : {
"gte" : 1559076401.0
}
}
}
]
}
All 3 queries return an empty response.
Hope you people can help. Thank you.

Answer 1

In elastic index, before inserting data, you you need define the fields mappings as date or numbers so that range searches can be applied.
Or keep dynamic mappings ON so that elastic can identify the field types automatically based on inserted data.
In case of latter, do check the auto generated mappings on your index.
Also check the date/timestamp format.

Answer 2

Since you are using epoch time, you need to mention that in the mapping. This is what I did. Basically the mapping and the way you stored the data mattered here. I am not sure if we can save any format as we want and query using any format we want. I will do some more research and update the answer if that can be done
1) created the mapping -- to show how the endTime mapping is done
2) inserting a few sample documents
3) queried the document using epoch time -- the way you wanted
Mapping
PUT so_test24
{
"mappings" : {
"_doc" : {
"properties" : {
"id" : {
"type" : "long"
},
"endTime" : {
"type" : "date",
"format": "epoch_millis"
}
}
}
}
}
Inserting the documents
POST /so_test24/_doc
{
"id": 1,
"endTime": "1546300800"
}
POST /so_test24/_doc
{
"id": 2,
"endTime": "1514764800"
}
POST /so_test24/_doc
{
"id": 3,
"endTime": "1527811200"
}
POST /so_test24/_doc
{
"id": 4,
"endTime": "1535760000"
}
The search Query
GET /so_test24/_search
{
"query": {
"range": {
"endTime": {"gte": "1532883892"}
}
}
}
The result
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 2,
"max_score" : 1.0,
"hits" : [
{
"_index" : "so_test24",
"_type" : "_doc",
"_id" : "uFIq42sB4TH56W1h-jGu",
"_score" : 1.0,
"_source" : {
"id" : 1,
"endTime" : "1546300800"
}
},
{
"_index" : "so_test24",
"_type" : "_doc",
"_id" : "u1Iq42sB4TH56W1h-zEK",
"_score" : 1.0,
"_source" : {
"id" : 4,
"endTime" : "1535760000"
}
}
]
}
}
