I know that Elasticsearch supports object and nested field type. According to my understanding they represent an individual object and an array of objects respectively. However, is it possible to have a field which is a hash-map of objects?

My use case is as follows –

• I want to be able to find a target object
• Modify only that target object
• Update that change in the Elasticsearch index

Currently, I am using the nested field type. The problem with that is for finding the target object I am having to loop through the entire array, make the change and then re-index. This will become expensive as my field starts having more and more objects

I know that I can do an _update_by_query using ctx but even that seems to loop through the field to find the target object.

Is there something that I am missing.

PS – I am a beginner in Elasticsearch
