Kiwix ranks by keyword overlap, which the package doc has said since it was written: "why is the sky blue" finds a TV episode. queryKiwix sent the whole Russian sentence, because the verbatim path added by V-508 skips the rewriter that would have reduced it. Measured against the Russian ZIM on 2026-08-09, over eight questions. Four reach the right article where they did not: TCP was "Перехват TCP-соединения" and is TCP, фотосинтез was "C4-фотосинтез" and is Фотосинтез, Линус Торвальдс was "Tux", and "кто написал Войну и мир" was "Радуйся, мир (Доктор Кто)". Two were already right and stay right. Two are still wrong and were wrong before. Nothing regressed. kiwix.Topic drops the narrative request, the interrogative and a verb behind one, and keeps everything else. A word it cannot classify is more likely the topic than noise. TitlePath tries the exact article first, since a ZIM is addressable by title and a wrong title is a 404. The gate this task set out to build does not exist. Query-to-passage cosine scored 0.79-0.91 on answerable questions and 0.75-0.84 on unanswerable ones, and the sets overlap. The wrong TCP article scored 0.8653, above five of six unanswerable rows. e5 measures topic, not whether the passage answers.
