Bookmark your results
Once you have created your lists you can add some of the search results into them.
First, make a search. On the search results page, next to each result there is a bookmark icon which will let you add that relevant result to a specific list.
When you get results, choose the ones you would like to add to a list and just click on the bookmark icon.
Choose the list and click on 'done'. You can also remove results from a list directly from this dropdown, just click the 'remove' button.
