WHY CAN'T I SEE ALL OF THE KEYWORDS?
I was looking for a keyword I couldn't recall. When I checked the Keyword list in the right side panel I noticed that the list stops at the work Oak.
I tried the Library Filter and it displays a little further, up to the phrase "OK Corral".
I know there are many other keywords.
I have a total of 4,838 keywords according to the Library Filter
Total of 160,000 images in the catalog.

LR chokes when it tries to display more than about 1500 keywords. This basic bug has been outstanding for more than six years and Adobe declines to fix it. The workaround is to introduce a hierarchy in your keywords and expand only part of the hierarchy at a time.
