How would we use your link? We go to the search page. In your web browser, look for a search icon at the top right of the page. On mobile, you may need to open up a context menu to find the search icon. You can probably just go to https://yourservername/search and get the same search page.
Copy your link and paste it into the search box, then press on the Search button. To save time for the future, you can make a bookmark to the search page.
