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 setting the environment variable ``WEAVIATE_URL``. Should not be specified if client is provided. weaviate_api_key: The Weaviate API key. If enabled and using Weaviate Cloud Services, get it from ``Details`` tab. Can be passed in as a named param or by setting the environment variable ``WEAVIATE_API_KEY``. Should not be specified if client is provided. batch_size: Size of batch operations. index_name: Index name. text_key: Key to use for uploading/retrieving text to/from vectorstore. by_text: Whether to search by text or by embedding. relevance_score_fn: Function for converting whatever distance function the vector store uses to a relevance score, which is a normalized similarity score (0 means dissimilar, 1 means similar). kwargs: Additional named parameters to pass to ``Weaviate.__init__()``. Example: .. code-block:: python from langchain_community.embeddings import OpenAIEmbeddings from langchain_community.vectorstores import Weaviate embeddings = OpenAIEmbeddings() weaviate = Weaviate.from_texts( texts, embeddings, weaviate_url="http://localhost:8080" ) rrXrN)r#r")r LangChain_rZ)r_r]r^r`)rNrOrIrPr)rarYr&r.rd configurer hexrschemaexists create_classrcrbkeysrrangelenrergflush)clsrirNrjrMrrrrrrPrIr-rYerrTrOrZ_rdrkrrlrmrnparamss r from_textszWeaviate.from_textss!@  4 2$   LL " "j " 9=Z }#=  X6}}##J/ MM & &v .9BY..u5 2;T)A,++-.  f JJw'E6;CJ6GH^EG,HEH \\ U$U+ 04d#((|002A/8|C/@,AAh #2", )'1!}F8$%%%//- 00 KKM3 6      !1    q G  6I  s*F&5GA4G& G/ F;;GGc x| td|D](}|jjj|*y)zUDelete by vector IDs.
