Is this example from the documentation

Is this example from the documentation complete? I tried this with my postgres db and local redis but I don't see the data in my vector DB:

from llama_index import Document
from llama_index.embeddings import OpenAIEmbedding
from llama_index.text_splitter import SentenceSplitter
from llama_index.extractors import TitleExtractor
from llama_index.ingestion import IngestionPipeline, IngestionCache
from llama_index.ingestion.cache import RedisCache


pipeline = IngestionPipeline(
transformations=[
SentenceSplitter(chunk_size=25, chunk_overlap=0),
TitleExtractor(),
OpenAIEmbedding(),
],
cache=IngestionCache(
cache=RedisCache(
redis_uri="redis://127.0.0.1:6379", collection="test_cache"
)
),
)

Ingest directly into a vector db

nodes = pipeline.run(documents=[Document.example()])
