  "ranked_by": "The task is split into words at punctuation and common words are dropped. Each remaining word is weighted by how rare it is in the catalog (ln(1 + rows / rows containing it), so a word found in few listings counts more than a word like get or price) and scores when it is found as a whole word, with a plural or -ing/-ed ending, or (5+ letters) as the start of a longer word in a listing's name, description or tags, or as a whole word in its host or URL path; the weight is multiplied by 1 plus 2 when the word is in the name, plus 1.5 when it is in one of P0's own tags, plus 2 when it is only in a service-specific host or URL. The sum is multiplied by 1 plus an evidence weight (P0 read the live 402 1.2, Agenstry saw a live 402 1.0, Open 402 verified 0.8, manifest-declared 0.7, manifest 0.6, registry 0.5). Ties: more unique sending wallets counted on-chain by P0 (where measured), then cheaper, then URL. At most 2 results come from one host while other hosts have matches.",
