Having run the report for 'Unused Keywords', I find I have several pages of "Unused Topic Keywords". Adobe help appears to differentiate between 'keywords' and 'indexed keywords' with no real explanation of the difference.
I have finally managed to get rid of most of the 'Unused Index Keywords' by deleting them from the Index pod. This pod is now displaying Index Keywords (key icon) and some Topic Keywords (key in a page icon). There are no bold entries in the Index pod for the Unused Topic Keywords.
How do I identify which topics contain the unused topic keywords?
There does not appear to be any way to do this other than opening every single topic in turn and inspecting the index page in properties and comparing it to the report list.
Surely, if the report can identify where there are unused topic keywords, there must be some method for a user to find the same?
