Qdrant

Qdrant (read: quadrant) is a vector similarity search engine. It provides a production-ready service with a convenient API to store, search, and manage points - vectors with an additional payload. Qdrant is tailored to extended filtering support.

安装与设置​

安装 Python 伴侣包：

pip install langchain-qdrant

嵌入模型​

FastEmbedSparse​

from langchain_qdrant import FastEmbedSparse

SparseEmbeddings​

from langchain_qdrant import SparseEmbeddings

向量存储​

围绕 Qdrant 索引存在一个包装器，允许您将其用作向量存储，无论是用于语义搜索还是示例选择。

要导入此向量存储：

from langchain_qdrant import QdrantVectorStore
