Lets say, I have 2 indices. IndexA and IndexB. IndexA has: name and id. IndexB has: id and salary I need to have name and corresponding salary to the same ID. ---

If you want one single document as a result, that won't be possible as elasticsearch does not support joins but if you want to get both documents, then that's a basic search across multiple indices. What is exactly your need? ---

If id from IndexA is equal to id from IndexB then increment the salary for that id by 300 ---

But does your data look like? Why do you have 2 indices? ---

The index is given as it is. We need to perform operations on given indices. ---

If you can't change the model to something which looks like a better practice, then you need to solve most likely all that on your application level, like: - run a scroll query on the first index and extract all the ids - run some bulk updates for each id to increase the value ---

Can this be done in a single request? ---

No. Only if you change your modeling. ---
