To/From Search Problem

When I search my emails and use the “From:”/“To:” fields to filter the results to a specific date range, I get nothing back. But when I eliminate those entries, I get everything back that fits the search criteria including those results in my date range of interest. Therefore, is there a certain format for the dates in the From:/To: fields that must be met for it to work? What I entered was: “1/1/2025” for the “From” field and “12/31/2025” for the “To” field.
