How to set ttl.

[songoo]

How can i set "ttl" "time to live" on index (so all results older than 60s would get removed from search for example https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-ttl-field.html)

i tried to use custom settings part:

"## Custom settings to apply when creating the index (optional)
elasticsearch.index.settings="{'_ttl' : { 'enabled' : true, 'default' : '60s' }"

But results are still searchable even after hour. is there need for another setting or have i set it with some kind of annotation? Currently have only one annotation
"@IndexType(name = "searchResult")
public class SearchResult extends Index { ..."

Or maybe is missing specification for timestamp (also some kind of annotation?)

Tnx for help.

Hello,

The ttl must be define on Mapping and not on Setting configuration
https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html

So you can add via this like annotation.

@IndexMapping(value = "{ searchResult : { "_ttl" : { "enabled" : true } } }")

Hello again, above code work well but i got to special situation. I reindex whole search every 4 hours
SearchResult searchResult = new SearchResult();
...
searchResult.index();
Always using same ids. I also have 12 ttl by annotation.

Expected : items that are not reindexed by "searchResult.index();" will expire after 12h others wil stay.
Reality : All items get deleted after 12h, even if they are reindexed 3 times.

Is there any way to update ttl while reindexing ?
