Hello,
I am using the PHP bindings to do a simple update of an index of about 60k documents via scroll. Basically I am just splitting one field of comma-separated values into two separate lists.
I am encountering something strange: All of my data is coming from elastic search in the following manner:
- Create scroll
- Iterate hits
- Update document fields
- Get new results from scroll ID
But there are a _lot_ of documents that are returned by scroll that when I try to update them I get a "document\_missing\_exception"... how can this be true? What's going on?
