Google 搜尋
本筆記本將說明如何使用 Google 搜尋元件。
首先，您需要設定正確的 API 金鑰和環境變數。 若要設定，請在 Google Cloud 憑證控制台中建立 GOOGLE_API_KEY (https://console.cloud.google.com/apis/credentials)，並使用可程式化搜尋引擎建立 GOOGLE_CSE_ID (https://programmablesearchengine.google.com/controlpanel/create)。 接下來，最好按照這裡找到的指示操作。
然後，我們需要設定一些環境變數。
%pip install --upgrade --quiet langchain-google-community
import os
os.environ["GOOGLE_CSE_ID"] = ""
os.environ["GOOGLE_API_KEY"] = ""
from langchain_core.tools import Tool
from langchain_google_community import GoogleSearchAPIWrapper
search = GoogleSearchAPIWrapper()
tool = Tool(
name="google_search",
description="Search Google for recent results.",
func=search.run,
)
