Glad to help. And mostly, yes. For instance, a search of "VLOOKUP" shows 3 topics (Handling of Empty Cells, Options, and Spreadsheet Functions), and the topic "Spreadsheet Functions" does include help for VLOOKUP, yet it doesn't take you to an anchor within the topic. So you have to search within that link for the actual VLOOKUP wording (which as you'd expect is also listed under LOOKUP, also on the same page).
As a result, the topics tend to be longer than necessary for a specific keyword / function.
