Setting hour in KQL or Lucene

[hadi_farzipour]

Hello
I have @timestamp field which is in following format

Jul 3, 2022 @ 06:55:55.153

How can I filter logs between 06:00 and 10:00 without mentioning days and months in KQL or Lucene query language.

I suppose you need runtime field or some sripts.

Thanks, However I do not want to use mapping solution in my issue, because in 8.x and later version it is not able to use mapping.

[Tomo_M (Tomohiro Mitani)]

Really? You can use runtime mappings also in 8.x.

I have resolved my problem by creating an scripted fields which contain following script.

return LocalDateTime.ofInstant(Instant.ofEpochMilli(doc['@timestamp'].value.millis),ZoneId.of('Iran')).getHour()
