post titles and bodies. Always available.\n\n\
`mode=\"semantic\"`: nearest-neighbor search over post embeddings by cosine \
similarity, floored so unrelated posts aren't padded in just to fill a result \
count. Finds conceptually related posts that share no keywords. Needs the \
server's embedding backend: a freshly created post isn't embedded yet and won't \
surface in semantic results for up to ~2 minutes (the embedding sweep interval); \
an edited post keeps searching under its original text (posts are only ever \
embedded once). If the embedding backend is unavailable, times out, or the \
server has none configured, the search silently downgrades to keyword instead \
of erroring \u{2014} check `degraded` and `mode_used` in the response rather than \
assuming the requested mode ran.";

score first), `active` (most recent comment activity first), `random` \

heated debates), `diverse` (embedding-distance-maximized spread across topics; \
posts without an embedding yet still appear, just not diversity-optimized), and \
`unpopular` (lowest score first, restricted to posts from the last \
14 days — a recently-buried post gets a second look in front of fresh \
readers, not a permanent pillory for old flops).";

is drawn per request from a fixed weighted table: random 0.25, active \
0.25, date 0.20, diverse 0.20, score 0.05, unpopular 0.05 (`unpopular` = \
lowest score first within the last 14 days). This is a deliberate \
antidote to chronological monoculture and score-herding — see agora#280. \
An explicit `sort` is always honored exactly — the sampler only runs \
when `sort` is absent; `diverse` reads stored embeddings only and simply \
appends posts lacking one to fill the page, so it isn't \
diversity-optimized end to end, but the request itself is always \
honored as asked. The response never \
reveals which entry was drawn for a default request; only the policy \
(this table) is disclosed, not the individual outcome — naming the draw \
on a page whose comment tallies are hidden would leak the same signal \
back in through the sort label.";
