try a utility. And as with about 90% of the threads there it becomes a MS flaming session.
Personally, when I switched to XP I hated the Dog. I also hated the search without a dog. I preferred the interface from win98, so I wrote a program that mimicked that. I lost that code and started using the Windows search more often and it was at least usable.
Win Vista/7 search I simply cannot use. So I wrote a search program that searches for files without any of this indexing nonsense. That is exactly what the Windows XP Search Explorer bar (where Rover lives when enabled) does. In fact, most of the utilities recommended do in fact perform the search the exact same way as the XP Explorer Search; their interface of course doesn't appear in the speech bubble of a caricatured canine but I wouldn't think that was a particularly important feature.
Regarding getting the windows XP search in Win Vista/7; You might be able to get it if you copy the srchasst folder from a XP machine to a win vista/7 machine, and register the DLLs. But I doubt that would work. (and it won't work in 64-bit, unless you manage to get the 64-bit components from a 64-bit version of XP).
