Search and replace "flat" but not hierarchical keywords in catalog

[30west]

Using other software, I am trying to stick to hierarchical (nested) keywords. Previously I was coached on how to use "Search and Replace" to remove the nested keywords leaving just the flat ones, but the list became too long and unwieldy.

Is it possible (in a similar fashion) to remove JUST the "flat ones, but leaving the hierarchical ones? I've tried a couple of format syntaxes (,keyword, or keyword,) but it's not working and I want to be careful to not delete the "nested" ones (parent | keyword).

I know that one can remove those manually per file, but clearly not practical with over 50k files.

As always, the expertise and help here will be appreciated....gary

I've tried a couple of format syntaxes (,keyword, or keyword,)

When you tried this, did you have "Treat repeating fields as single string" checked?

Good. Just want to note that you wouldn't want to do ", keyword," as it will essentially end up joining the preceding and subsequent keywords into one, but "keyword," should be fine.

Thanks Andy or that clarification. I hadn't actually tried it yet but was planning to when I had a bit of time. A good backup is always my best friend.
