SaveableVectorStore

Returns a string representing the type of vector store, which subclasses must implement to identify their specific vector storage type.

Method to add documents to the memory vector store. It extracts the text from each document, generates embeddings for them, and adds the resulting vectors to the store.

Method to add vectors to the memory vector store. It creates MemoryVector instances for each vector and document pair and adds them to the store.

Creates a VectorStoreRetriever instance with flexible configuration options.

Deletes documents from the vector store based on the specified parameters.

Return documents selected using the maximal marginal relevance. Maximal marginal relevance optimizes for similarity to the query AND diversity among selected documents.

Saves the current state of the vector store to the specified directory.

This method must be implemented by subclasses to define their own serialization process for persisting vector data. The implementation determines the structure and format of the saved data.

Searches for documents similar to a text query by embedding the query and performing a similarity search on the resulting vector.

Method to perform a similarity search in the memory vector store. It calculates the similarity between the query vector and each vector in the store, sorts the results by similarity, and returns the top k results along with their scores.

Searches for documents similar to a text query by embedding the query, and returns results with similarity scores.

Static method to create a FakeVectorStore instance from an array of Document instances. It adds the documents to the store.

Static method to create a FakeVectorStore instance from an array of texts. It creates a Document for each text and metadata pair, and adds them to the store.

The name of the serializable. Override to provide an alias or to preserve the serialized module name in minified environments.

Implemented as a static method to support loading logic.

Loads the documents.
