Unless it has changed in the 2020 or 2021 version you will find that QB does not even search the transaction notes field. After spending $$ on support call and requesting this for 10yrs!!!, it still has not changed. So don't hold your breath. We were told to use this field to record shipment UPS data with the invoice, found you cannot search or report on it. Basically data in the transaction note field is unreachable unless you are on the invoice or sales receipt for that note.  Sorry for being the downer here.
