如何从搜索查询中插入数据以进行弹性搜索

Question

I try to copy some data from one elastic db to another elasticsearch db, is there any way to insert data from query results?

Example of results:

{
  "took": 29,
  "timed_out": false,
  "_shards": {
    "total": 2,
    "successful": 2,
    "failed": 0
  },
  "hits": {
  "total": 572,
  "max_score": 1,
  "hits": [
    {
      "_index": "ref",
      "_type": "dic",
      "_id": "12345",
      "_score": 1,
      "_source": {
        "name": "Test name"
      }
    },
    ...
  ]
}

In each db mapping is equals.

I fork some project witch make a bulk data for elasticsearch, json-to-es-bulk

I it's compability with 5.6 es version, you can use it in 2 variants:

`node index.js -f inputdata.json --index newIndexName --type newIndexType --rewrite true`

or

`node index.js -f inputdata.json --index --type --rewrite false`

after run, you'll see a file request-data.txt, just use it to POST /_bulk [request-data.txt content]

Input data json file must contains an array of search hits, like this:

[ { "_index": "oldIndexName", "_type": "oldIndexName", "_id": "SOME_ID-HiTfm", "_score": 1, "_source": { "orderNumber": "2984", "refId": "SOME_VALUE" } }, ... ]
