Hello,

I got this exception [1] when running a search query on ES 7.6.2:

```auto
    {
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "titles.POL": {
                  "query": "Wniosek"
                }
              }
            }
          ]
        }
      },
      "from": 0,
      "size": 10
    }

```

I got the issue since I did a shrink (18 -\> 6) followed by a split (6 -\> 24). What can be the cause of this issue?

Thank you!
