Drop ivfflat index on contact_embeddings (breaks search on small tables) - #40
Merged
Conversation
An ivfflat index with lists=100 + default probes=1 makes ORDER BY <=> queries scan only 1 of 100 clusters, silently returning zero rows on a small table. For a personal contact store an exact sequential scan is fast and correct. The live index is already dropped; this stops ai:setup from recreating it.
