Failing to match "53...\n" with "[0-9][0-9]\\.\\.\\.\n?" in Discover filter. Help?

Elastic Stack Kibana

Huh - thank you - that worked...

{
  "query": {
    "regexp": {
      "dlog.line.keyword": {
        "value": "[0-9][0-9]*\\.\\.\\.\n"
      }
    }
  }
}

successfully matched the lines precisely starting with some digits followed by literal dots.

So .keyword actually means 'the actual data' and the field name is... a set of words?

It's a bit surprising - might be worth adding something to the documentation about this.

How would I go about making that suggestion?

Thanks again.
