Reranking

Upstash Search combines semantic and full text search results for maximum relevancy. Optionally, you can re-rank the returned documents using a state of the art model to further improve relevancy.

We provide this additional re-ranking as an opt-in setting because it requires more computational resources and is charged at $1 per 1K re-ranked documents.

scores = index.search(
    query="space opera",
    limit=2,
    reranking=True,
)

scores = index.search(
    query="space opera",
    limit=2,
    reranking=True,
)

const searchResults = await index.search({
  query: "space opera",
  limit: 2,
  reranking: true,
});
