Subject: [PATCH] Drop subreddit front pages from degoog results
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Its Reddit engine returns a community's landing page for any query at all — a question about ZFS
scrubs came back with Rocket League Esports and Dividend Investing, interleaved one in two, so
half of what reached the model was noise. Threads from that same engine are frequently the best
result there is, so the engine stays and only the URL shape goes: /r/<name> with nothing after it
is a front page by definition. That is a fact about the URL, not an opinion about how well it
matches, and this file does no similarity scoring of its own.
