> In LUCENE-5879, we added auto-prefix terms, where the terms dict finds good prefix terms to index, so that at search time PrefixQuery and TermRangeQuery can visit far fewer terms than the full set.
> WildcardQuery and RegexpQuery will only make use of auto-prefix terms if it's "effectively" a PrefixQuery (e.g. WildcardQuery("foo*")), but we could fix them so they could also use auto-prefix terms for other cases (e.g. foo?b*) though in practice it's less likely to have an impact I think.
