Elasticsearch 集成

!pip -q install langchain-elasticsearch

from langchain_elasticsearch import ElasticsearchEmbeddings

# 定义模型 ID
model_id = "your_model_id"

# 使用凭据实例化 ElasticsearchEmbeddings
embeddings = ElasticsearchEmbeddings.from_credentials(
    model_id,
    es_cloud_id="your_cloud_id",
    es_user="your_user",
    es_password="your_password",
)

# 为多个文档创建嵌入向量
documents = [
    "This is an example document.",
    "Another example document to generate embeddings for.",
]
document_embeddings = embeddings.embed_documents(documents)

# 打印文档嵌入向量
for i, embedding in enumerate(document_embeddings):
    print(f"Embedding for document {i + 1}: {embedding}")

# 为单个查询创建嵌入向量
query = "This is a single query."
query_embedding = embeddings.embed_query(query)

# 打印查询嵌入向量
print(f"Embedding for query: {query_embedding}")

# 创建 Elasticsearch 连接
from elasticsearch import Elasticsearch

es_connection = Elasticsearch(
    hosts=["https://es_cluster_url:port"], basic_auth=("user", "password")
)

# 使用 es_connection 实例化 ElasticsearchEmbeddings
embeddings = ElasticsearchEmbeddings.from_es_connection(

# 为多个文档创建嵌入向量

]
document_embeddings = embeddings.embed_documents(documents)

# 打印文档嵌入向量

# 为单个查询创建嵌入向量
query = "This is a single query."
