When normal search returns proper result but when trying query with taxonomy field it returns
Sorry, something went wrong.
Detail => Unexpected response data from server.
one of the list or document library column is not mapped with Managed Metadata field.
go to document library setting and check all the managed metadata field.
For me after creating the document library, I re-created the taxonomy term set again.
Be careful when you delete taxonomy term. you’d better change the value not delete the termset.
If still specific metadata is not showing by search result
-> full craw
-> if still not showing edit the item in the list(or document library) and set the value again and then incremental crawl
