I was searching my Yahoo! Mail(tm) yesterday and got a surprise as search results. Before that I want to get it in records that the search feature of yahoo mail sucks! It takes a lot of time to get back the results unlike the popular Gmail.
Back to Yahoo! Mail search results. I did a search for a string in my inbox for some messages in the last month. The results yahoo gave me looked foreign to me (see image above). On closer inspection none of the emails listed in the results belonged to me! Out of curiosity, I did another search and got the results I wanted. Attempts to recreate the original problem did not give me results from other users though. But the possibility of the mixup happening during search of yahoo mail indicates that they have a bug in their search system(atleast). I hope the performance is much better with their new email-client like interface they are developing.
