Bootstrap inline text box and search button

Try using input groups: https://getbootstrap.com/docs/4.4/components/input-group/ this puts the button next to the textfield and makes it one component

This answer comes from the original poster's comment:

<div class="input-group">
  <input id="address" type="text" placeholder="City or Zipcode" class="form-control">
  <span class="input-group-btn">
    <button class="btn btn-default" type="button" id="addressSearch">Search</button>
  </span>
</div>
