Sometimes when searching in Kibana I will get a pop up about failed shards. Inspecting the response shows errors like this one:  
`The length of [message] field of [32] doc of [my-index] index has exceeded [1000000] - maximum allowed to be analyzed for highlighting. This maximum can be set by changing the [index.highlight.max_analyzed_offset] index level setting. For large texts, indexing with offsets or term vectors is recommended`  
The error is clear about what the problem is and how to fix it. But what is not clear to me is how to identify the offending document. I initially assumed that `32` was the documents `_id`, but no such document exists in the index in question. Generally, all documents in my index have alphanumeric hashes as their `_id`, but the error message always shows an integer. Is there any way I can use the integer from the error message to identify the document?

Welcome to our community! 😃

Is there anything in the Elasticsearch logs at this time that might help?
