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,)

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