In both 'global search' and 'filter section notes' it seems not be possible to search by a 'state icon'.
For instance, a search for 'pin' (icon name appear hovering over the mouse pointer) is not listed in the search results.
I also tried to search for both system:pin and value:pin, but without success.
Then I noticed that by creating a perspective list and grouping by 'icon' I could obtain the icon 'number', which is '3' for pin. But searching by system:3 and value:3 didn't return anything.
Could you please consider adding support for searching by state icon 'name'?
Thank you,
Carlos
