      Parameters:
      embedding - The embedding to be added to the store.
      Returns:
      The auto-generated ID associated with the added embedding.

    • add

      void add(String id, Embedding embedding)
      Adds a given embedding to the store.
      Parameters:
      id - The unique identifier for the embedding to be added.

    • addAll

      List<String> addAll(List<Embedding> embeddings)
      Adds multiple embeddings to the store.
      Parameters:
      embeddings - A list of embeddings to be added to the store.
      Returns:
      A list of auto-generated IDs associated with the added embeddings.

    • addAll

      default List<String> addAll(List<Embedding> embeddings, List<Embedded> embedded)
      Adds multiple embeddings and their corresponding contents that have been embedded to the store.
      Parameters:
      embeddings - A list of embeddings to be added to the store.
      embedded - A list of original contents that were embedded.
      Returns:
      A list of auto-generated IDs associated with the added embeddings.

    • generateIds

      default List<String> generateIds(int n)
      Generates list of UUID strings
      Parameters:
      n - - dimension of list

    • addAll

      default void addAll(List<String> ids, List<Embedding> embeddings, List<Embedded> embedded)
      Adds multiple embeddings and their corresponding contents that have been embedded to the store.
      Parameters:
      ids - A list of IDs associated with the added embeddings.
      embeddings - A list of embeddings to be added to the store.
      embedded - A list of original contents that were embedded.

    • remove

      default void remove(String id)
      Removes a single embedding from the store by ID.
      Parameters:
      id - The unique ID of the embedding to be removed.

    • removeAll

      default void removeAll(Collection<String> ids)
      Removes all embeddings that match the specified IDs from the store.
      Parameters:
      ids - A collection of unique IDs of the embeddings to be removed.

    • removeAll

      default void removeAll(Filter filter)
      Removes all embeddings that match the specified Filter from the store.
      Parameters:
      filter - The filter to be applied to the Metadata of the TextSegment during removal. Only embeddings whose TextSegment's Metadata match the Filter will be removed.

    • removeAll

      default void removeAll()
      Removes all embeddings from the store.

    • search

      EmbeddingSearchResult<Embedded> search(EmbeddingSearchRequest request)
      Searches for the most similar (closest in the embedding space) Embeddings.
      All search criteria are defined inside the EmbeddingSearchRequest.
      EmbeddingSearchRequest.filter() can be used to filter by various metadata entries (e.g., user/memory ID). Please note that not all EmbeddingStore implementations support Filtering.
      Parameters:
      request - A request to search in an EmbeddingStore. Contains all search criteria.
      Returns:
      An EmbeddingSearchResult containing all found Embeddings.
