Import index by third party?
I'm working on an update to a textbook of the usual cinderblock size and heft. A late step will be, of course, to generate an index. Exactly how and what balance between proper concept indexing and keyword indexing isn't determined yet, but it's going to be more or less the author's task (both as SME and as in "I don't wanna do it"). But in looking at the process to offload this on the non-ID, non-InCopy, typical-Word-user author... I can't seem to find it. Everything revolves around entering the indexing info in InDesign — which as author/editor, is how I've always done it.
Isn't there a process to import a plain text topic list? Other than vague handwaving about "go find the INDD file with the list," are there any specific guidelines about how to structure such file for hierarchical entries, see-alsos, and the like? Or am I imagining that this alternative approach even exists?
Do I have to import a Word file to a simple InDesign file in order to do this? Or... what?
(The Adobe help page makes no mention of anything but importing an INDD file.... which is mildly embarrassing in light of certain conversations.)
