If you already know the search query url of the target website, use 'quill' (without quotes) as the query word in that url and paste it in the *Submit URL field.

Alternatively if you are not aware of the search query url, go through the following instructions to get the Submit URL

1. Go to the target website's search page. The target can be any web site which provides the option to search. It could be your personal home page or blog.
   
   Let's consider the Hindi Wikipedia page at hi.wikipedia.org as an example. This page has hindi content, but the search box on the left doesn't let you type in Hindi. So we'll try to get a QuillSearch box that would let us type in hindi to search the site
   
   
2. Search for quill on the search page (hi.wikipedia.org in this case)

3. Copy the URL; which in the example we are considering would be
   http://hi.wikipedia.org/wiki/%E0%A4%B5%E0%A4%BF%E0%A4%B6%E0%A5%87%E0%A4%B7:Search?search=quill
   from the browser once the search results appear, and paste it in the *Submit URL field of this QuillSearch registration page.
   
   (Note that the search results you get when you search for the word 'quill' do not matter.)

That is it! Fill in your name and email address in the form and click on the Submit button to get the html for the iframe and anchor tags that you can include in your website for using QuillSearch.
