 ## Vector Store Usage
 
 Use a vector store to store embedded data and perform vector search.
 
 ```python
 from langchain_google_sapnner import SpannerVectorstore
 from langchain.embeddings import VertexAIEmbeddings
 
 embeddings_service = VertexAIEmbeddings()
 vectorstore = SpannerVectorStore(
  instance_id="my-instance",
  database_id="my-database",
  table_name="my-table",
  embeddings=embedding_service
 )
 ```
 
 See the full [Vector Store][vectorstore] tutorial.
 
 ## Document Loader Usage
 
 Use a document loader to load data as LangChain `Document`s.
