The left side menu allows you to
Below the editor, and not visible at first, you will see the structure with each individual fragment that was identified highlighted in red. Running the mouse over the list of results on the right changes this display.

The right side display (where this help is now) will show a value for the fragment (a bit number, atomic partial polar surface), a description of the identified fragments for the chosen method, the actual SMARTS, and the atom numbers comprising the fragment (the atoms that matched that SMARTS). Running the mouse over any value in the row will show the structure (on the left below the editor) with the fragment represented by that SMARTS highlighted in red.

Here is a sample output.
