Vim: How to make IDEAVim highlight usages on right sidebar like it does for CTRL+F (Find)?

Had this feature working on Windows, but lost it when moving to Mac, hopefully someone can tell me how to re-enable this useful feature?

If you use the built-in Find on a word, the right side of the IDE scroll-bar area will show a yellow notch for every occurance.  You can quickly see if there are occurances throughout your file.

Using the Vim plugin IDEAVim's search /fooBar you will be able to search for occurances in the file, but the sidebar does not show the yellow notches for the occurances. 

How do I get those yellow notches back now that I'm on a Mac?
