Metaphor(EXA) 基于大语言模型的搜索引擎
文章目录
关于 Metaphor
Metaphor是基于大语言模型的搜索引擎,允许用户使用完整的句子和自然语言搜索,还可以模拟人们在互联网上分享和谈论链接的方式进行查询内容。
Metaphor同时还能与LLMs结合使用,允许LLMs连接互联网,查询自己知识库外部的内容。

使用示例
安装环境
!pip install exa_py
!pip install langchain
!pip install llama_hub
!pip install llama_index
- api_key 为从官网 https://exa.ai 注册后,个人的 key
- 过去使用 MetaphorToolSpec,后面改为使用 ExaToolSpec
from llama_hub.tools.exa.base import ExaToolSpec
metaphor_tool = ExaToolSpec( api_key="xxx" )
metaphor_tool_list = metaphor_tool.to_tool_list()
for tool in metaphor_tool_list:
print(tool.metadata.name)
'''
search
retrieve_documents
search_and_retrieve_documents
search_and_retrieve_highlights
find_similar
current_date
'''
metaphor_tool.search('machine learning transformers', num_results=3)
