Give the different Icons multiple names (kind of like tags), such that it's easier to search through them and find the right one.

Prime example is the Dove and Crow Icons, which can't be found through "Bird" but only either "Dove" or "Crow". Same goes for many other Icons. Introducing these "tags" would make it much easier to find Icons.

Have multiple possible matches for icon names so one may find an image without getting only the one exact match. (I find myself frequently perusing the ENTIRE list to find one that I don't remember the name of).
