I wanted to tell you a bit about how the search works in the documentation for 12.2.
When you do a search on the 12.2 documentation, in addition to giving you the sections that match your criteria, it gives you a few other categories of info:
The results on the left are the general search - what sections of what books best match your criteria.
The first box on the right, "Refine Results," is links to refined searches - to concepts, tasks, and examples that match your criteria. If you're searching for a specific procedure, then seeing examples or tasks is a quick way to narrow your search down, and concepts can be helpful if you're looking for background information.
The second box on the right, "Top Matching Books," is links to the top level of the books that best match your search. If you're looking for a general topic and all of the explanation and related procedures, this can be a useful tool.
