1. Choose the related query and right click to choose "Rename" option, rename the query name as "rel"

2. Navigate to Home ribbon, click "Advanced Editor". Copy and paste the below codes into the opening window:

let
  Source = #table(
      {"Score"},
      List.Zip(
          {{
              "Call me on 08588812885",
              "Call me on 07525812845",
              "I need assitance please call me",
              "Last tried in 2019"
            }}
        )
    ),
  #"Added Custom" = Table.AddColumn(Source, "Custom", each Text.Split([Score], " ")),
  #"Added Custom1" = Table.AddColumn(
      #"Added Custom",
      "Custom.1",
      each Text.Combine(
          List.Select(
              [Custom],
              (l) => [
                        ListOfCharacters = Text.ToList(l),
                        Result = not (List.Count(ListOfCharacters) >= 10
                                    and List.AllTrue(
                                            List.Transform(ListOfCharacters, (x) => List.Contains({"0".."9"}, x))
                                    )
                    )][Result]
            ), " ")
    )
in
    #"Added Custom1"
