I am using Java21, SpringBoot and Elasticsearch. I have documents in Elasticsearch index. This index must be as much reliable as possible and sometimes retunrs not matching results or nothing depending on server state. My question is how u would defined the index health ?

Check if ES is on, Comparing documents count to db count. This could be nice second step..

Comparing documents count to db count. This could be nice second step

That's what I was doing in the past. During the night, I was running batches (reports) to check at least that the number of docs per month was accurate.

That's from a functional point of view.

From a technical perspective, I'd just rely on what the _search API gives back:

  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
  }

If there's something in failed, then I'd warn the user. Otherwise I'd assume that the data is correct.

My 2 cents
