On Windows, using NVDA:

When you press the New Note button, you're taken inside the correct field, but the label is wrong, it announces "search notes all notes". I don't really think the field needs a label. What does need a label is the search button under the search
field, which currently doesn't have one. Also, arrowing down from that search button, NVDA reads "table with zero rows and zero columns grid", I don't know what that is but if that random info could somehow be
hidden from the screen-reader that'd be great.

Start by reproducing the New Note and search interactions on Windows with NVDA, focusing on the search field, search button, and the announced grid. Done means the New Note field has an appropriate announcement, the search button has a label, and the empty grid information is hidden from the screen reader.
