Partial Updates in ElasticSearch Using olivere/elastic in Go

When managing data in ElasticSearch, it becomes essential to understand how to update records. While the official ElasticSearch documentation provides comprehensive information on the UPDATE API, finding specific guidance for integrating it with the olivere/elastic library in Go can be challenging. This question explores precisely this topic, providing a solution for updating a specific field within a document.

The provided code snippet demonstrates how to partially update a document. It begins by initializing the Update function, specifying the index, type, and ID of the document to be updated. The Doc method is then used to define the fields that need to be updated. In this case, only the location field is being updated with the value stored in the message variable. Finally, the Do function executes the update operation and returns an update response object.

It's important to note that an alternative approach, involving the use of Groovy scripts, was attempted but did not yield successful results. The provided code snippet highlights the successful method for partially updating records using the olivere/elastic library in Go.
