## haystack_integrations.components.retrievers.pinecone.embedding_retriever

### PineconeEmbeddingRetriever

Retrieves documents from the `PineconeDocumentStore`, based on their dense embeddings.

Usage example:

```python
import os
from haystack.document_stores.types import DuplicatePolicy
from haystack import Document
from haystack import Pipeline
from haystack.components.embedders import SentenceTransformersTextEmbedder, SentenceTransformersDocumentEmbedder
from haystack_integrations.components.retrievers.pinecone import PineconeEmbeddingRetriever

os.environ["PINECONE_API_KEY"] = "YOUR_PINECONE_API_KEY"
document_store = PineconeDocumentStore(index="my_index", namespace="my_namespace", dimension=768)

documents = [Document(content="There are over 7,000 languages spoken around the world today."),
             Document(content="Elephants have been observed to behave in a way that indicates..."),
             Document(content="In certain places, you can witness the phenomenon of bioluminescent waves.")]

document_embedder = SentenceTransformersDocumentEmbedder()
document_embedder.warm_up()
documents_with_embeddings = document_embedder.run(documents)

document_store.write_documents(documents_with_embeddings.get("documents"), policy=DuplicatePolicy.OVERWRITE)

query_pipeline = Pipeline()
query_pipeline.add_component("text_embedder", SentenceTransformersTextEmbedder())
query_pipeline.add_component("retriever", PineconeEmbeddingRetriever(document_store=document_store))
query_pipeline.connect("text_embedder.embedding", "retriever.query_embedding")

query = "How many languages are there?"

res = query_pipeline.run({"text_embedder": {"text": query}})
assert res['retriever']['documents'][0].content == "There are over 7,000 languages spoken around the world today."
```

#### __init__

```python
__init__(
    *,
    api_key: Secret = Secret.from_env_var("PINECONE_API_KEY"),
    index: str = "default",
    namespace: str = "default",

```

Creates a new PineconeDocumentStore instance.

It is meant to be connected to a Pinecone index and namespace.

**Parameters:**

- **api_key** (<code>Secret</code>) – The Pinecone API key.
- **index** (<code>str</code>) – The Pinecone index to connect to. If the index does not exist, it will be created.
- **namespace** (<code>str</code>) – The Pinecone namespace to connect to. If the namespace does not exist, it will be created
  at the first write.
- **batch_size** (<code>int</code>) – The number of documents to write in a single batch. When setting this parameter,
  consider [documented Pinecone limits](https://docs.pinecone.io/reference/quotas-and-limits).

- **spec** (<code>dict\[str, Any\] | None</code>) – The Pinecone spec to use when creating a new index. Allows choosing between serverless and pod
  deployment options and setting additional parameters. Refer to the
  [Pinecone documentation](https://docs.pinecone.io/reference/api/control-plane/create_index) for more
  details.
  If not provided, a default spec with serverless deployment in the `us-east-1` region will be used
  (compatible with the free tier).
- **metric** (<code>Literal['cosine', 'euclidean', 'dotproduct']</code>) – The metric to use for similarity search. This parameter is only used when creating a new index.
- **show_progress** (<code>bool</code>) – Whether to show a progress bar when upserting documents. Set to False to disable
  (e.g. in tests or scripts where quiet output is preferred).
