InMemoryDocumentStore (original) (raw)

The InMemoryDocumentStore is a very simple document store with no extra services or dependencies.

It is great for experimenting with Haystack, however we do not recommend using it for production.

InMemoryDocumentStore requires no external setup. Simply use this code:

from haystack.document_stores.in_memory import InMemoryDocumentStore

document_store = InMemoryDocumentStore()

InMemoryBM25Retriever: A keyword-based Retriever that fetches documents matching a query from a temporary in-memory database.

InMemoryEmbeddingRetriever: Compares the query and document embeddings and fetches the documents most relevant to the query.
