<!DOCTYPE html>
<html>
  <head>
    <!-- bootstrap -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">    
    <!-- select2 -->
    <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/css/select2.min.css" rel="stylesheet" />

    <!-- select2-bootstrap4-theme -->
    <link href="select2-bootstrap4.min.css" rel="stylesheet">
  </head>

  <body>

    <div class="container mt-5">
      <h3>Example of <a href="https://github.com/ttskch/select2-bootstrap4-theme" target="_blank">@ttskch/select2-bootstrap4-theme</a></h3>
      <hr>

      <form>
        <div class="form-group">
          <label>Example select</label>
          <select class="form-control" id="select-single" placeholder="Choose one thing" data-allow-clear="1">
            <option></option>
            <option>1</option>
            <option>2</option>
            <option>3</option>
            <option>4</option>
            <option>5</option>
          </select>
        </div>
        <div class="form-group">
          <label>Example multiple select</label>
          <select multiple class="form-control" placeholder="Choose anything" data-allow-clear="1">
            <option>1</option>
            <option>2</option>
            <option>3</option>
            <option>4</option>
            <option>5</option>
          </select>
        </div>
      </form>
    </div>

    <!-- bootstrap -->
    <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

    <!-- select2-bootstrap4-theme -->
    <script src="script.js"></script>
  </body>
</html>

This is how it should be provided to the user This is how it should shown

But instead of this it's showing this for me:

What am I missing in my html why it does not show the searchbar?

Because there is no detail about your script.js my proposal is:

$('select').each(function(idx, ele) {
    $(ele).select2({
        theme: 'bootstrap4',
        placeholder: ele.getAttribute('placeholder')
    });
});
