Two Yellows, No Greens: Search by Letters, Not Positions
A real Wordle (#1,920), a 1,952-word haystack, and what a letters-only search is actually for: getting you from a two-yellow opener to a six-word cluster. Then the cluster itself — the problem no finder solves, and the one Word Solver is built for.
There's a Wordle board every player knows: your opener comes back with a yellow or two and not a single green. A couple of letters are definitely in the word, but you know nothing about where they go beyond "not there." Everything you know is about letters. None of it is about positions.
