The email search only shows the more recent emails. How I fix it?

Until last week I could search any email from my Inbox. But now I can only see those from December.|||I am also having a problem with the email Search for the Inbox for Yahoo Mail, except it is the opposite of the problem that the first poster has. I don't get a "hit" on an email I had received on December 1, 2010, but would get a "hit" on other emails I received on November 30th and earlier. I tried about 10 different word searches and all had the same results. I am using Yahoo Mail Plus.





I tried using Advanced Search and made sure the items to be searched including the Inbox and the message body, but still had the same problem, did not get a hit on the email received on December 1.|||There seems to be ongoing problem with Yahoo email message search beginning sometime late Nov 2010. Search arguments, clearly evident in messages, even on the current page, whether in Sender, Subject, or message content fields, are not recognized in the search (or, in case of multiple messages which should be caught, some are not returned). Hope they can deal with this before they merge with AOL, which has its own problems.
