Defining field aliases¶

Add comment alias pointing to the content field¶

PUT /reviews/_mapping
{
  "properties": {
    "comment": {
      "type": "alias",
      "path": "content"
    }
  }
}

Using the field alias¶

GET /reviews/_search
{
  "query": {
    "match": {
      "comment": "outstanding"
    }
  }
}

Using the "original" field name still works¶

GET /reviews/_search
{
  "query": {
    "match": {
      "content": "outstanding"
    }
  }
}
