Input configuration options for initializing a retriever that extends
the BaseRetriever class. This interface provides base properties
common to all retrievers, allowing customization of callback functions,
tagging, metadata, and logging verbosity.
Fields:
callbacks (optional): An array of callback functions that handle various
events during retrieval, such as logging, error handling, or progress updates.
tags (optional): An array of strings used to add contextual tags to
retrieval operations, allowing for easier categorization and tracking.
metadata (optional): A record of key-value pairs to store additional
contextual information for retrieval operations, which can be useful
for logging or auditing purposes.
verbose (optional): A boolean flag that, if set to true, enables
detailed logging and output during the retrieval process. Defaults to false.
