When viewing a Saved Search results page, there are asterisks on some lines.
The asterisk on the Results tab of the Saved Search indicates that the line is the main line of the transaction.
If the saved search is not filtered by Main Line, then it will return the line with the asterisk followed by the line items.
To filter out the line with asterisk, add the criterion Main Line is False (No).
To return only the lines with asterisk, add the criterion Main Line is True (Yes).
