View Key Parameters of Existing Queries

This helps you in refining your searched query or adding additional fields to query thereby saving the time of moving out of the current interface.

This can be done by clicking on View Stats icon.

When you click on the icon, it will launch window showing stats for different fields with respective counts for the query. You can choose the required field from the drop-down menu and check the required options.  

Once you have selected the required field, click on Add. You will see the query being formed in Combine Search with query identifier (your existing query).
