It should be milliseconds. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

@Binh, thank you, you are right, I find the reference here: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. but the problem is that, the TTL doesn't work when indexing a document, while it works when defined in type mapping. The user encountered the same problem with me: > Actually I don't know why.

That is correct, the \_ttl field is disabled by default: [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-ttl-field.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-ttl-field.html) To use TTL, you need to enable it first in the mapping and then after that you can index documents with a TTL value and it will work as expected. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

@Binh, enable ttl first in mapping and then use it in REST or client, it make sense. Thank you again!
