## Installation

$ $ES_HOME/bin/plugin install org.codelibs/elasticsearch-reindexing/2.3.0

## Usage

### Run Reindexing

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":{}}}'

### Check Reindexing process

Sending GET request, you can check current processes for reindexing:

$ curl -XGET localhost:9200/_reindex

### Stop Reindexing process

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
