How do I delete all X days old documents from the Java API?

EDIT:

To clarify, the question is "how do I write a query for documents that are X days old so I can delete them".

END OF EDIT

Our code indexes results from a query using ElasticSearch. We want to run a clean up job once a day to delete all old documents. We currently do so by calling an external script, but to cut down on the dependencies we would love to do it from Java.

I can't figure out how to query for the old documents using the API... Clues, help?

Solution

  • If you delete documents which have been stored for a certain amount of time you can set a TTL (time-to-live) parameter, setting the documents deletion bit-set flag once this time has elapsed. See here. Hope this is an alternative you could consider.

    UPDATE

    "query":{
  "match_all": {}
},
"filter":{
  range:{
   "field":{
     lte: 20140225,
     gte: 20140201
    } 
  }
}
