To be able to copy a link to certain search results:
Perform the search and adjust the filters as desired.
Click the "Save Search" link.
Give a descriptive name to the search being saved. Upon clicking "Create", you'll be redirected to your search results.
Copy the URL in the address bar. That's the search link. It's most likely long. I recommend using a link shortener such as Bitly.
Note: To subsequently view your saved searches, navigate to "Your Account" section of the website. Click the appropriate "Searches" link.
