The Search History button allows you to find previous searches and repeat them, without having to remember all of the criteria used to perform the search. This feature is specific to your searches and you can choose the dataset of interest you would like to pull previous searches from. It can be found as a tab below the search bar. Note Search History retains information for your current session only.
After opening your Search History, choose the Dataset of interest and then click on the play icon to the left of the search you want to repeat. You can also name searches here by entering text into the Named Search column, and utilize the refine columns to help you determine which search you may want to repeat.
