Requirement: Make multi-line plain text field searchable from AllItems page.
What I've done so far: Created new site-level column, "Notes", added it to my list, created a new managed property, "NotesProperty", and configured the below settings to be searchable, queryable, and retrievable (https://mstechtalk.com/create-multiline-text-field-searchable/).
However, it's been several hours but when I try testing it out it's still not working. Am I missing something obvious??
