如何将一些ElasticSearch数据复制到新索引 [英] How to copy some ElasticSearch data to a new index

问题描述

假设我的ElasticSearch中有电影数据，我是这样创建的：

Let's say I have movie data in my ElasticSearch and I created them like this:

curl -XPUT "http://192.168.0.2:9200/movies/movie/1" -d'
{
    "title": "The Godfather",
    "director": "Francis Ford Coppola",
    "year": 1972
}'

我有很多电影不同的年份。我想复制特定年份（所以是1972年）中的所有电影，并将它们复制到新的索引 70sMovies，但是我看不到该怎么做。

And I have a bunch of movies from different years. I want to copy all the movies from a particular year (so, 1972) and copy them to a new index of "70sMovies", but I couldn't see how to do that.

推荐答案

自ElasticSearch 2.3开始，您现在可以使用内置的 _reindex API

Since ElasticSearch 2.3 you can now use the built in _reindex API

例如：

POST /_reindex
{
  "source": {
    "index": "twitter"
  },
  "dest": {
    "index": "new_twitter"
  }
}

或仅通过添加过滤器/查询的特定部分

Or only a specific part by adding a filter/query

POST /_reindex
{
  "source": {
    "index": "twitter",
    "query": {
      "term": {
        "user": "kimchy"
      }
    }
  },
  "dest": {
    "index": "new_twitter"
  }
}
