You can now save a search query & settings and use it to search again later. This can be helpful if a user is searching something very specific and couldn't find what they were looking for at that time, this allows them to easily run the same search again at a later point. To turn it on go to manage > Service Types > Search
and toggle on Save Search (shown below).
Once turned on the save search will show up in your results page below. You can click on save search, name the search and it will save for a later time.
