In SharePoint Online I have a document library with a column "HFMetadataStatus". This column is just a "single line of text" property and has a default value of "unset".
I copied 1000 files in the library and all of them got "HFMetadataStatus = unset" as exspected.
When I used the SharePoint Search with the query "Querytext": "HFMetadataStatus: unset" I got all items of this library as a result.
On the next day I changed the value from "unset" to "Done" on all files.
After one week I searched again for "Querytext": "HFMetadataStatus: unset" and expected to get zero results, because I updated the property.
But unfortunately I still get the exact same result like before my change.
How can this be? Anybody has an idea what might go on here? I added HFMetadataStatus as a managed property of cause, but the index seems not to be updated for any reason.
How can I debug that?
