Store a dense vector and a sparse vector on each record in a single Pinecone index, then query both signals in one request. Pinecone combines them server-side. Because sparse (BM25-style) scores are unbounded, you set the balance between the two signals client-side, by scaling the query vectors before the request (an `alpha` weighting). This is the Vectors API single-index hybrid pattern. ## Normalize sparse and dense values A single index that stores both vector types doesn't reconcile their score ranges. Dense-vector scores fall in a bounded range (roughly `[-1, 1]` for `dotproduct` on unit-norm embeddings), while BM25-style sparse weights are unbounded and can run into double digits. Without explicit weighting, the sparse component dominates the combined score. To make the two signals comparable, apply a **convex combination** at query time using an `alpha` parameter: - `combined = alpha * dense + (1 - alpha) * sparse` - `alpha = 1.0` ranks by dense only (pure semantic). - `alpha = 0.0` ranks by sparse only (pure keyword). - `alpha = 0.5` weights the two signals equally. Pinecone applies this weighting by **scaling the query vectors before sending them to the index** (the index itself stores raw values). Use the [`hybrid_score_norm`](#hybrid-single-5-alpha) helper documented in the walkthrough below; it multiplies the dense values by `alpha` and the sparse values by `1 - alpha`, so the underlying dotproduct produces the desired combination. ### Choosing alpha There's no universal best value — alpha depends on your data and query distribution. Reasonable starting points: - **`alpha = 0.75`** (dense-leaning) — a good default for natural-language queries on conversational or document-style content. - **`alpha = 0.5`** (balanced) — useful when keyword and semantic signals contribute equally (e.g., mixed exact-match and synonym queries). - **`alpha = 0.25`** (sparse-leaning) — good for queries with high keyword specificity (product SKUs, technical IDs, named entities). We recommend evaluating multiple alpha values against a labeled relevance set drawn from your own workload. ## Set up and search To perform hybrid search with a single index that stores both dense and sparse vectors, follow these steps: :::::steps :::step{title="Create the index"} To store both dense and sparse vectors in a single index, use the [`create_index`](/guides/database-2026-04-control-plane-create-index) operation, setting the `vector_type` to `dense` and the `metric` to `dotproduct`. This is the only combination that supports dense/sparse search on a single index. ```python Python theme={null} from pinecone.grpc import PineconeGRPC as Pinecone from pinecone import ServerlessSpec

with explicit weighting"} For a conceptual overview of why this normalization is needed, see [Normalize sparse and dense values](#normalize-sparse-and-dense-values). Because Pinecone views your sparse-dense vector as a single vector, it doesn't offer a built-in parameter to adjust the weight of a query's dense part against its sparse part; the index is agnostic to density or sparsity of coordinates in your vectors. You may, however, incorporate a linear weighting scheme by customizing your query vector, as demonstrated in the function below. The following example transforms vector values using an alpha parameter. ```Python Python theme={null} def hybrid_score_norm(dense, sparse, alpha: float): """Hybrid score using a convex combination alpha * dense + (1 - alpha) * sparse Args: dense: Array of floats representing sparse: a dict of `indices` and `values` alpha: scale between 0 and 1 """ if alpha < 0 or alpha > 1: raise ValueError("Alpha must be between 0 and 1") hs = { 'indices': sparse['indices'], 'values': [v * (1 - alpha) for v in sparse['values']] } return [v * alpha for v in dense], hs ``` The following example transforms a vector using the above function, then queries a Pinecone index. ```Python Python theme={null} sparse_vector = { 'indices': [10, 45, 16], 'values': [0.5, 0.5, 0.2] } dense_vector = [0.1, 0.2, 0.3] hdense, hsparse = hybrid_score_norm(dense_vector, sparse_vector, alpha=0.75) query_response = index.query( namespace="example-namespace", top_k=10, vector=hdense, sparse_vector=hsparse ) ``` ::: ::::: ## Related pages - [Hybrid search overview](./index-data-search-hybrid-search.md) - [Run hybrid search on separate indexes](./index-data-search-hybrid-search-separate-indexes.md) - [Reciprocal rank fusion](./index-data-search-reciprocal-rank-fusion.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
