delete

Example:

from langchain_redis import RedisVectorStore
from langchain_openai import OpenAIEmbeddings

vector_store = RedisVectorStore(
    index_name="langchain-demo",
    embedding=OpenAIEmbeddings(),
    redis_url="redis://localhost:6379",
)

# Assuming documents with these ids exist in the store
ids_to_delete = ["doc1", "doc2", "doc3"]

result = vector_store.delete(ids=ids_to_delete)
if result:
    print("Documents were succesfully deleted")
else:
    print("No Documents were deleted")

Note:

• If ids is None or an empty list, the method returns False.
• If the number of actually deleted keys differs from the number of keys submitted for deletion the method returns False
• The method uses the drop_keys functionality from RedisVL to delete the keys from Redis.
• Keys are constructed by prefixing each id with the key_prefix specified in the configuration.
