The trial version is a fully functional program which will allow you to create a search for your website.  However, when a visitor uses the trial version to search your site, the first result will be replaced with a link to our site. You will need to purchase the program and open the saved file in the registered version and save.  This process will remove our link from your search and replace it with the correct first result.  

 

After saving, you will need to upload the files again, replacing the ones which were uploaded with the trial program.
