This is a pure Qdrant config change - no vector updates needed. Qdrant still expects float inputs, handles conversion internally. Args: collection_name: Name of collection to quantize. quantization_type: Type of quantization to apply (“int8” or “binary”). rescore: Whether to enable rescoring for accuracy (default: True). Raises: ProviderError: If quantization application fails. ### Method: `collection_info` [Section titled “Method: collection_info”](#method-collection_info) ** ``` collection_info() ``` Get the collection metadata. ### Method: `create_payload_index` [Section titled “Method: create_payload_index”](#method-create_payload_index) ** ``` create_payload_index() ``` Create a payload index on the specified field. Args: collection_name: Name of the collection. field_name: Name of the payload field to index. key_type: field value’s data or schema type (what category of data will be indexed) Raises: ProviderError: Qdrant operation failed. Returns: UpdateResult: Response from Qdrant after creating the index. ### Method: `delete_by_file` [Section titled “Method: delete_by_file”](#method-delete_by_file) ** ``` delete_by_file() ``` Delete all chunks for a specific file. Args: file_path: File path to remove from index. ### Method: `delete_by_files` [Section titled “Method: delete_by_files”](#method-delete_by_files) ** ``` delete_by_files() ``` Delete all chunks for multiple files in a single operation. Args: file_paths: List of file paths to remove from index. ### Method: `delete_by_id` [Section titled “Method: delete_by_id”](#method-delete_by_id) ** ``` delete_by_id() ``` Delete chunks by their unique identifiers. Args: ids: List of chunk IDs to delete. ### Method: `delete_by_name` [Section titled “Method: delete_by_name”](#method-delete_by_name) ** ``` delete_by_name() ``` Delete chunks by their unique names. Args: names: List of chunk names to delete. ### Method: `delete_collection` [Section titled “Method: delete_collection”](#method-delete_collection) ** ``` delete_collection() ``` Delete a vector store collection. Args: collection_name: Name of collection to delete. If None, uses configured collection. Returns: bool: True if collection was deleted, False if it didn’t exist. Raises: ProviderError: If client is not initialized or operation fails. ### Method: `get_collection` [Section titled “Method: get_collection”](#method-get_collection) ** ``` get_collection() ``` Get collection details. Args: collection_name: Name of the collection to retrieve. Returns: Collection information as CollectionInfo from Qdrant. Raises: ProviderError: If client is not initialized or operation fails. ### Method: `handle_persistence` [Section titled “Method: handle_persistence”](#method-handle_persistence) ** ``` handle_persistence() ``` This is no-op, but implemented by the memory provider to trigger persistence. ### Method: `list_collections` [Section titled “Method: list_collections”](#method-list_collections) ** ``` list_collections() ``` List all collections in the Qdrant instance. Returns: List of collection names. Raises: ConnectionError: Failed to connect to Qdrant server. ProviderError: Qdrant operation failed. ### Method: `migrate_from` [Section titled “Method: migrate_from”](#method-migrate_from) ** ``` migrate_from() ``` Migrate data from a source client to this provider’s client. Args: source_client: Source Qdrant client. collection_names: Specific collections to migrate (default: all). batch_size: Batch size for scrolling and upserting. Raises: ProviderError: If client is not initialized. ### Method: `migrate_to` [Section titled “Method: migrate_to”](#method-migrate_to) ** ``` migrate_to() ``` Migrate data from this provider’s client to a destination client. Args: dest_client: Destination Qdrant client. collection_names: Specific collections to migrate (default: all). batch_size: Batch size for scrolling and upserting. Raises: ProviderError: If client is not initialized. ### Method: `search` [Section titled “Method: search”](#method-search) ** ``` search() ``` Search for similar vectors using dense, sparse, or hybrid search. Args: vector: Query vector (StrategizedQuery or list of floats/ints or dict for hybrid other inputs will be deprecated in favor of StrategizedQuery in the future). query_filter: Optional filter for search results. Returns: List of search results sorted by relevance score. Raises: CollectionNotFoundError: Collection doesn’t exist. SearchError: Search operation failed. ### Method: `upsert` [Section titled “Method: upsert”](#method-upsert) ** ``` upsert() ``` Insert or update code chunks with hybrid embeddings. Args: chunks: List of code chunks with embeddings to store. Raises: CollectionNotFoundError: Collection doesn’t exist. UpsertError: Upsert operation failed.
