Update
editUpdate
editThe update API allows updates of a specific document using the given script.
In the following example, we will index a document that also tracks how many times a character has said the given quote, and then we will update the times
field.
'use strict' const { Client } = require('@elastic/elasticsearch') const client = new Client({ node: 'http://localhost:9200' }) async function run () { await client.index({ index: 'game-of-thrones', id: '1', body: { character: 'Ned Stark', quote: 'Winter is coming.', times: 0 } }) await client.update({ index: 'game-of-thrones', id: '1', body: { script: { lang: 'painless', source: 'ctx._source.times++' // you can also use parameters // source: 'ctx._source.times += params.count', // params: { count: 1 } } } }) const { body } = await client.get({ index: 'game-of-thrones', id: '1' }) console.log(body) } run().catch(console.log)
With the update API, you can also run a partial update of a document.
'use strict' const { Client } = require('@elastic/elasticsearch') const client = new Client({ node: 'http://localhost:9200' }) async function run () { await client.index({ index: 'game-of-thrones', id: '1', body: { character: 'Ned Stark', quote: 'Winter is coming.', isAlive: true } }) await client.update({ index: 'game-of-thrones', id: '1', body: { doc: { isAlive: false } } }) const { body } = await client.get({ index: 'game-of-thrones', id: '1' }) console.log(body) } run().catch(console.log)
