I have a for fee Yahoo email account. I tested the search system this morning. The queries returned a null set. The result message I received appears below:
I was unable to locate a way to query Yahoo about this problem. As a paying customer, I expect a system to work and to have an Apple style “report a problem” button available to me. At this point, I don’t know if the search issue is one specific to me or if it is an indication that a larger, more severe problem exists within the Yahoo mail search function.
