Removing Data From ElasticSearch

Question

I m new to ElasticSearch  I m trying to figure out how to remove data from ElasticSearch  I have deleted my indexes  However  that doesn t seem to actually remove the data itself  The other stuff I ve seen points to the Delete by Query feature  However  I m not even sure what to query on  I know my indexes  Essentially  I d like to figure out how to do a   DELETE FROM  Index    From PostMan in Chrome  However  I m not having any luck  It seems like no matter what I do  the data hangs around  Thus far  I ve successfully deleted the indexes by using the DELETE HTTP Verb in PostMan and using a url like      http   localhost 9200  indexName    However  that doesn t seem to actually remove the data  aka docs  themselves

For mass-delete by query you may use special delete by query API:

$ curl -XDELETE 'http://localhost:9200/twitter/tweet/_query' -d '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

In history that API was deleted and then reintroduced again

Who interesting it has long history.

In first version of that answer I refer to documentation of elasticsearch version 1.6. In it that functionality was marked as deprecated but works good.
In elasticsearch version 2.0 it was moved to separate plugin. And even reasons why it became plugin explained.
And it again appeared in core API in version 5.0!

You can delete either whole index doc-type or a perticular id data  these are the three ways    curl -XDELETE localhost 9200 index name curl -XDELETE localhost 9200 index name doc-type curl -XDELETE localhost 9200 index name doc-type documentId   and if you wish to delete all the index then go for wildcard

To list down the indices curl -L localhost 9200  cat indices  9200 default port change the port if using some other port   You will likely find all indices starting with logstash-yyyy-mm-dd format logstash-    You can see all the indices and use  To delete the indices and data trigger following command   curl -XDELETE localhost 9200 index name  Which will remove the data and indices both

The documentation  or The Definitive Guide  says  that you can also use the next query to delete all indices  curl -XDELETE  http   localhost 9200     And there s an important note   For some  the ability to delete all your data with a single command is a very scary prospect  If you want to eliminate the possibility of an accidental mass-deletion  you can set the following to true in your elasticsearch yml  action destructive requires name  true

You can delete one or more indices  which really deletes their files from disk  For example   curl -XDELETE localhost 9200  INDEXNAME   Where  INDEXNAME can be an index name  e g  users v2   N indices separated by comma  e g  users v2 users v3   An index pattern  e g  users    or  all  also works  unless it s blocked in the config via action destructive requires name  true   Deleting individual documents is possible  but this won t immediately purge them  A delete is only a soft delete  and documents are really removed during segment merges  You ll find lots of details about segments and merges in this presentation  It s about Solr  but merges are from Lucene  so you have the same options in Elasticsearch   Back to the API  you can either delete individual documents by ID  provide a routing value if you index with routing    curl -XDELETE localhost 9200 users v2  doc user1   Or by query   curl -XPOST -H  Content-Type  application json  localhost 9200 users v2  delete by query -d       query          match            description field    bad user
