# 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.
