So from what I can see the search loads fine. It could be your database that is a bit slow.
What you can do is to add a graphic spinner to your search to indicate that the results are loading. This would give your users some form of visual aid letting them know that the search is working.
To add the spinner just select it from your search filter editor.
Using this will allow your site not to hit the database each time a search is done.
Secondly, the search doesn't have any default css but rather relies on the theme or your chosen custom css to display the form in a way you want. I see it is currently using the bootstrap to style the form because the bootstrap classes are being used.
For the blank search form you will need to separate the search form itself from the results. This can be done when inserting your search onto the page. You will be presented with the option to Insert the Search form with results, Search form only, or results form only.
So you will need to add the search form only to the page and then on a separate page add the results . It should be noted that the results page will also have the search form attached.
Please let me know if this is clear or if further clarification is needed.
