I changed a managed metadata column in a library to use a different set, but the new term set contains the same terms (or a subset - reused in the term management).
I've noticed that filtering on the column does not work after the change. I guess this is because the copied terms have different internal ID even though they refer to the same term.
Is this something that will eventually work after the taxonomy update scheduled job has run, or do I need to set the managed metadata values again on all the items in the library?
to reproduce, e.g.
"MyDocumentLibrary" has a column "MetadataCol" which is of managed metadata type, using termset "MySetA", containing term "Term1"
I add a document, and tag it with "Term01"
I reuse "Term1" in another set "MySetB"
I switch the column "MetadataCol" to use "MySetB" instead of "MySetA"
Result: When filtering on "Term1", I get no results.
When inspecting Term1, I find that it is present in both term sets (i.e is a single identical term)
