I want to update a value in the document when a condition is met. By using Transform script can i update a value of the document.

Hey,

a transform is only changing the payload of the [watch execution context](https://www.elastic.co/guide/en/elastic-stack-overview/6.4/how-watcher-works.html#watch-execution-context), but does not modify any documents. If you want to do that, you need to use the [index action](https://www.elastic.co/guide/en/elastic-stack-overview/6.4/actions-index.html)
