Elasticsearch Reindexing Plugin provides a feature to create a new index from an existing index. If you want to add new analyzers or make changes to existing fields, you need to re-create your index.

To re-index your index, send the following request:
localhost:9200/{fromindex}/{fromtype}/_reindex/{toindex}/{totype}
fromtype and totype is optional. If you want to create "newsample" index from "sample" index, run:
$ curl -XPOST localhost:9200/sample/_reindex/newsample/
{"acknowledged":true,"name":"8e0c3743-41ea-4268-aa81-d4c38058a407"}
A value of "name" is a reindexing name(ex. 8e0c3743-41ea-4268-aa81-d4c38058a407). To wait for the reindexing process, use "wait_for_completion":
$ curl -XPOST localhost:9200/sample/_reindex/newsample/?wait_for_completion=true
Sending reindexing data to a remote cluster, use "url":
$ curl -XPOST localhost:9200/sample/_reindex/newsample/?url=http%3A%2F%2Flocalhost%3A9200%2F
Delete old index after reindexing:
$ curl -XPOST localhost:9200/sample/_reindex/newsample/?deletion=true
To specify your query,
$ curl -XPOST localhost:9200/sample/_reindex/newsample -d '{"query":{"match_all":{}}}'
Sending GET request, you can check current processes for reindexing:
$ curl -XGET localhost:9200/_reindex
To stop a reindexing process, send DELETE request by the reindexing name:
$ curl -XDELETE localhost:9200/_reindex/{name}
For example,
$ curl -XDELETE localhost:9200/_reindex/8e0c3743-41ea-4268-aa81-d4c38058a407
