Restore prior capability within "Advanced search filters"
Per https://help.yahoo.com/kb/new-yahoo-mail/overview-yahoo-mail-sln36709.html and my own testing, your New Email Advanced search filter no longer includes a "key word" search box, only To/From/Subject. Please restore the ability to find an email based solely on key word(s) within the body of the message. Omitting such a search method severely limits the ability to find Who-sent-that email content.
