A technical blog post details a strategy for updating embedding models in large-scale search systems. The author argues that re-embedding an entire corpus is costly and can lead to a temporary period where data exists in two different vector spaces, causing noise. To mitigate this, the post proposes re-embedding documents in order of query demand, which significantly improves recall compared to random ordering or keeping two encoders active simultaneously without proper normalization. The strategy aims to minimize the negative impact of model migration on search performance. AI
