Do you also experience that the search feature in yahoo email does not work?

I've had one of my accounts since 1999 with all my important emails in it. When I do a word search to find certain emails, nothing comes from the result even if I know 100% it is in there and I eventually find manually (in a small percentage of cases because it is impossible to go through thousands of emails). I now use gmail but am I the only one who experiences this major problem?|||The search feature hasn't been working correctly for the past few months, for some it's sporadic. Yahoo said they are trying to get it fixed, they didn't say how long it will take.
