We wanted to let you know that we're aware that 'Title and Description Search' is currently not displaying all items correctly. We've identified the steps we need to take to resolve the issue, and expect to have fixed it by the end of next week. We realise how frustrating this is, and will try to resolve the issue as soon as possible.
If you're a seller and the item you're selling is not displaying in a Title and Description Search, please contact Customer Support. They'll refund your fees once they've confirmed that your item is affected.
If you're a buyer, these items are always available by using Title-only Search (which can be run by unticking the 'Include title and description' box when running a search). You may also consider temporarily changing any 'Favourite Searches' you have set up to search by Title only.
Regards,
The eBay Team
