json/update

This endpoint allows you to update attribute values in documents, same as SphinxQL’s UPDATE syntax. Syntax is similar to json/insert, but this time the doc property is mandatory.

Example:

{
  "index":"test",
  "id":1,
  "doc":
  {
    "gid" : 100,
    "price" : 1000
  }
}

The daemon will respond with a JSON object stating if the operation was successfull or not:

 {
  "_index": "test",
  "_id": 1,
  "result": "updated"
}

The id of the document that needs to be updated can be set directly using the id property (as in the example above) or you can do an update by query and apply the update to all the documents that match the query:

{
  "index":"test",
  "doc":
  {
    "price" : 1000
  },

  "query":
  {
    "match": { "*": "apple" }
  }
}

Query syntax is the same as in the json/search endpoint. Note that you can’t specify id and query at the same time.

To update a document in a cluster’s index cluster property should be set along with index property:

{
  "cluster":"nodes4",
  "index":"test",
  "id":1,
  "doc":
  {
    "gid" : 100,
    "price" : 1000
  }
}
