PLEASE bring back the search feature that existed in the previous versions of Yahoo mail that allowed me to do a filtered advance search by keyword and date range in a particular folder. I relied on this feature for years to be able to do my work and by removing this function, it is almost impossible for me to find particular emails I need without having to go though hundreds of search results. I have 25 years of emails and the sudden loss of this feature has left me feeling desperate as do not know how I can continue to do my work without it.
