In Crelate, you have the ability to run database queries and both save and delete those searches.
For more information on our search, please navigate to the link here: Using Search
Once you have run your search, you may use the search drop down in the top left of your screen to then save that search (see below). Additionally, this will provide a menu of any additional saved searches along with your 5 most recent unsaved searches.
To later delete that search, you may again use the drop down (if your search is not already selected) to select that search. Next, you'll see a menu of 'Actions.' Within that list, you'll see the option to delete.
