Searching by Tags in Bridge - can it be done?

I use Bridge as the file manager for all my thousands of photos and finding folders by name is not a problem. But I recently realised that there is an option to add tags to every photo when saving it in Photoshop. So I have trialled this with the contents of a few recent folders, assuming that then there would be some kind of search engine in Bridge which would allow me to find the relevant photos of e.g. my stepson regardless of what folder he might be in by looking for his name. But I can find no such way of searching and thus I am wondering what is the point of the tags option when saving a photo? Am I missing something or is the only way to set up searching at this granular level to use the Keywords Panel in Bridge? It doesn't make sense to me for Photoshop seemingly to offer something that has no user value.
