Can you please help us to know, how to identify which index(en\_y\_\*\*) relates to which document(denmod\_y\_\*\*\*\*) . ---

`a previous copy of the primary shard existed but can no longer be found on the nodes in the cluster`: I don't think there's any way to recover that. Especially since we don't know how this happened. I don't fully understand the question about the document and the index. Generally, when you find / retrieve a document it should return it's metadata including `_index`. ---

Thanks for the answer. Let me give it clearly with the screenshot, as per that you could see en\_y\_\*\* is an index and below that a field displaye as denmod\_y\_\*\*\*\*. please help me to understand what it actually says. ![Snapshot_01082019](https://us1.discourse-cdn.com/elastic/original/3X/5/f/5fe895c35efeb50d01bc8558e037adc8c4073965.png) ---

TBH I don't know what that is — it's not one of our tools. But what you are displaying is a field name or value? Depending on that you could either find it in the mappings or with a query. Though I'm not sure how this relates to the problem. ---

Even after making the indices to green by manually allocating primary shards to a node, Now again the index status is showing in red status. Also the unassigned shards are increased from 132 to 634 now. > Kindly help us on this issue again. ---
