        """Construct Weaviate wrapper from raw documents.
        This is a user-friendly interface that:
            1. Embeds documents.
            2. Creates a new index for the embeddings in the Weaviate instance.
            3. Adds the documents to the newly created Weaviate index.
        This is intended to be a quick way to get started.
        Args:
            texts: Texts to add to vector store.
            embedding: Text embedding model to use.
            metadatas: Metadata associated with each text.
            client: weaviate.Client to use.
            weaviate_url: The Weaviate URL. If using Weaviate Cloud Services get it
                from the ``Details`` tab. Can be passed in as a named param or by
