I get about 200. My filter designates it as a Wittman Tailwind if the aircraft model is a "Tailwind" or a "Tail Wind" or variations of W-8, W-9, or W-10 (with dash, or with a space, or no dash or space). There are still a number of false hits, so I don't include Tailwinds in my "standard" set.
[Edit: This erroneously said "get about 2000". The number was actually 200.]
Searching Tailwinds is difficult, since some of the designations (e.g., "W10") are used for other aircraft types as well (Augusta AW109SP or VIRUS SW 100, for instance) and you end up with false hits. The false hits are reduced if you don't use wild cards (e.g., "W-8" vs. "W-8*") but then you lose the examples where the builder reverses the order (N214SS, for instance, a "W-8 TAILWIND").
If there are more reliable search terms, I'd be glad to use them.
