隐喻搜索 (Metaphor Search)

隐喻搜索是一个完全为LLMs设计的搜索引擎。您可以搜索并获取任何页面的内容。

本笔记本介绍了如何使用隐喻搜索。

首先，您需要设置正确的API密钥和环境变量。在这里获取每月1000次免费搜索。

然后将您的API密钥输入为环境变量。

import os

os.environ["METAPHOR_API_KEY"] = "..."

使用他们的SDK (Using their SDK)

这是使用Metaphor API的较新且更受支持的方式 - 通过他们的SDK

# !pip install metaphor-python

from metaphor_python import Metaphor

client = Metaphor(api_key=os.environ["METAPHOR_API_KEY"])

from langchain.agents import tool
from typing import List

@tool
def search(query: str):
    """使用查询调用搜索引擎。"""
    return client.search(query, use_autoprompt=True, num_results=5)

@tool
def get_contents(ids: List[str]):
    """获取网页的内容。
    
    传入的ids应该是从`search`中获取的id列表。
    """
    return client.get_contents(ids)

@tool
def find_similar(url: str):
    """获取与给定URL相似的搜索结果。
    
    传入的url应该是从`search`返回的URL。
    """
    return client.find_similar(url, num_results=5)

tools = [search, get_contents, find_similar]

使用工具包装器 (Using the tool wrapper)

这是使用Metaphor的旧方法 - 通过我们自己的内部集成。

from langchain.utilities import MetaphorSearchAPIWrapper

search = MetaphorSearchAPIWrapper()

调用API

results接受一个经过Metaphor优化的搜索查询和结果数量（最多500个）。它返回一个包含标题、URL、作者和创建日期的结果列表。
