问题背景：
我想通过Google或者其他网站通过精准搜索确认该产品是否存在，但是即使该产品不存在Google也会返回一些相关的url链接，现在想通过python实现搜索结果的精准匹配以确认该产品是否为正确的名称【可以通过google搜索到，如果搜索不到则认为该产品不存在】，以下为精准结果截图
实现代码：
import requests
from bs4 import BeautifulSoup
def is_product(product):
query = product.replace(' ', '+')
query = '"'+query+'"'
add = '&sca_esv=396701017a0fe9d3&sca_upv=1&sxsrf=ADLYWIKWgdKR0hofOSCSRshq3fR-z5vDMA%3A1715482705794&ei=UTBAZqCXMMvK1e8Pw_C8gAk&ved=0ahUKEwjgg7CKj4eGAxVLZfUHHUM4D5AQ4dUDCBE&uact=5&oq=%22%E6%96%B0%E8%83%BD%E6%BA%90%E6%B1%BD%E8%BD%A6%E7%94%B5%E6%B1%A0%22&gs_lp=Egxnd3Mtd2l6LXNlcnAiFyLmlrDog73mupDmsb3ovabnlLXmsaAiMgYQABgeGA8yBhAAGB4YDzIGEAAYHhgPMggQABiABBiiBDIIEAAYgAQYogQyCBAAGIAEGKIESP8FUABYAHAAeACQAQCYAeIBoAHiAaoBAzItMbgBA8gBAPgBAvgBAZgCAaAC5QGYAwCSBwMyLTGgB8kC&sclient=gws-wiz-serp'
URL = f"https://www.google.com/search?q={query}&as_q={query}&tbs=li:1"
print(URL)
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36"
}
resp = requests.get(URL, headers=headers)
decoded_text = resp.text
# print(">>>" * 20)
# print(decoded_text)
# print(">>>" * 20)
results = []
if resp.status_code == 200:
soup = BeautifulSoup(resp.content, "html.parser")
# print(soup)
for g in soup.find_all('div', class_='tF2Cxc'):
title = g.find('h3').text
link = g.find('a')['href']
item = {
"title": title,
"link": link
}
results.append(item)
print(results)
else:
print("Failed to fetch search results")
return True if len(results)>=1 else False
query = '"新能源汽车电池"'
query = '"高档数控机床用变频智能电动执行器（电动夹爪）"'
query = '"CAE—多学科设计集成与优化"'
res = []
for query in ["新能源汽车电池","高档数控机床用变频智能电动执行器（电动夹爪）","CAE—多学科设计集成与优化"]:
res.append(is_product(query))
print(res)
