To use this, you need to have `meilisearch` python package installed, and a running Meilisearch instance. To learn more about Meilisearch Python, refer to the in-depth Meilisearch Python documentation: https://meilisearch.github.io/meilisearch-python/. See the following documentation for how to run a Meilisearch instance: https://www.meilisearch.com/docs/learn/getting_started/quick_start. Example: .. code-block:: python from langchain_community.vectorstores import Meilisearch from langchain_community.embeddings.openai import OpenAIEmbeddings import meilisearch # api_key is optional; provide it if your meilisearch instance requires it client = meilisearch.Client(url='http://127.0.0.1:7700', api_key='***') embeddings = OpenAIEmbeddings() embedders = { "theEmbedderName": { "source": "userProvided", "dimensions": "1536" } } vectorstore = Meilisearch( embedding=embeddings, embedders=embedders, client=client, index_name='langchain_demo', text_key='text') Nlangchain-demotextmetadata) embeddersct|||}||_||_||_||_||_||_|jjt|jj||_ y)z#Initialize with Meilisearch client.rrrN) r _client _index_name _embedding _text_key _metadata_key _embeddersindexstrupdate_embedders_embedders_settings) self embeddingrrr index_nametext_key metadata_keyr&s r__init__zMeilisearch.__init__Qsq v3H %#!)##'<<#5#5   !$  9 %  defaultc  t|}g}|+|Dcgc] }tjj"}}||Dcgc]}i}}|jj |}t |D]H\} } || } || } | | |j<|| } |jd| d|| i|j| iJ|jjt|jj||Scc}wcc}w)a!Run more texts through the embedding and add them to the vector store.
