You will find a search bar at the top of the tables within the interface. This search bar can be used to refine your results by using one or more filters. By clicking on the filter symbol on the top right next to the search bar, you can find the "quick filters", which are most commonly used.

By clicking into the search bar, all the filters drop down (you will see “Popular Filters” on top, all the other filters can be found when scrolling down). Once you've selected a filter, select and enter the criteria for the filter and confirm by hitting the enter button.

Example:

You can refine you results by selecting the Reference Price (enter a number) and the Grade (Condition) types you want to return in the table (see below). You can add as many filters as you need to.
