I am using olivere/elastic library for elasticsearch in my go app . I have list of values for a particular field (say fieldA) of elasticsearch document. I want to update a particular field of all document by searching on field fieldA .
This : Updating a record in ElasticSearch using olivere/elastic in google go explains the update part. But in my case in don't have Id of documents to be updated . So, either i can make search call to retrieve document ids and then update them , or is there another way am missing? Thanks in Advance.
If you need to update a list of documents, you can use the Update By Query API. The unit tests give you a hint about how the syntax looks like. However, if you have individual values for individual documents, I guess there's no other way than updating them one by one. The fastest way to achieve that is by using the Bulk API.
