通用搜索函数
创建一个可复用的搜索脚本：
bash
python -c "
from duckduckgo_search import DDGS
import json
def web_search(query, search_type='text', max_results=5, region='wt-wt', timelimit=None):
'''
执行 DuckDuckGo 搜索
参数:
query: 搜索关键词
search_type: 搜索类型 (text, news, images, videos)
max_results: 最大结果数
region: 地区 (cn-zh, us-en, wt-wt)
timelimit: 时间限制 (d, w, m, y)
'''
with DDGS() as ddgs:
if search_type == 'text':
results = list(ddgs.text(query, region=region, timelimit=timelimit, max_results=max_results))
elif search_type == 'news':
results = list(ddgs.news(query, region=region, timelimit=timelimit, max_results=max_results))
elif search_type == 'images':
results = list(ddgs.images(query, region=region, max_results=max_results))
elif search_type == 'videos':
results = list(ddgs.videos(query, region=region, timelimit=timelimit, max_results=max_results))
else:
results = []
return results
# 使用示例
query = 'Python 3.12 new features'
results = web_search(query, search_type='text', max_results=5)
print(f'🔍 搜索: {query}')
print(f'📊 找到 {len(results)} 个结果')
print()
for i, r in enumerate(results, 1):
print(f\"{i}. {r['title']}\")
print(f\" {r['href']}\")
print(f\" {r['body'][:150]}...\")
print()
"
搜索并保存结果
bash
python -c "
from duckduckgo_search import DDGS
import json
from datetime import datetime
query = 'latest tech news'
output_file = f'search_results_{datetime.now().strftime(\"%Y%m%d_%H%M%S\")}.json'
with DDGS() as ddgs:
results = list(ddgs.text(query, max_results=10))
# 保存到 JSON 文件
with open(output_file, 'w', encoding='utf-8') as f:
json.dump({
'query': query,
'timestamp': datetime.now().isoformat(),
'results': results
}, f, ensure_ascii=False, indent=2)
print(f'✅ 搜索结果已保存到: {output_file}')
print(f'📊 共 {len(results)} 条结果')
"
多关键词批量搜索
bash
python -c "
from duckduckgo_search import DDGS
import time
queries = [
'Python best practices 2024',
'React vs Vue 2024',
'AI development tools'
]
all_results = {}
with DDGS() as ddgs:
for query in queries:
print(f'🔍 搜索: {query}')
results = list(ddgs.text(query, max_results=3))
all_results[query] = results
print(f' 找到 {len(results)} 个结果')
time.sleep(1) # 避免请求过快
print()
print('=' * 50)
print('📊 搜索汇总')
print('=' * 50)
for query, results in all_results.items():
print(f'\n🔎 {query}:')
for i, r in enumerate(results, 1):
print(f\" {i}. {r['title'][:60]}...\")

错误处理

python -c "
from duckduckgo_search import DDGS
from duckduckgo_search.exceptions import DuckDuckGoSearchException
try:
with DDGS() as ddgs:
results = list(ddgs.text('test query', max_results=5))
print(f'✅ 搜索成功，找到 {len(results)} 个结果')
except DuckDuckGoSearchException as e:
print(f'❌ 搜索出错: {e}')
except Exception as e:
print(f'❌ 未知错误: {e}')
"
使用代理
如果需要使用代理：
bash
python -c "
from duckduckgo_search import DDGS
# 设置代理
proxy = 'http://127.0.0.1:7890' # 替换为你的代理地址
with DDGS(proxy=proxy) as ddgs:
results = list(ddgs.text('test query', max_results=5))
print(f'通过代理搜索成功，找到 {len(results)} 个结果')
"
常见问题
安装失败？
bash
# 确保 pip 是最新版本
pip install --upgrade pip
pip install duckduckgo-search
# 或使用 uv
uv pip install duckduckgo-search
搜索无结果？
bash
# 检查网络连接
# 尝试使用代理
# 减少搜索关键词复杂度
# 检查地区设置是否正确
请求被限制？
bash
# 在多次搜索之间添加延迟
import time
time.sleep(1) # 等待 1 秒
# 减少单次请求的结果数量
max_results=5 # 而不是 50
与其他工具集成
结合 browser-use 获取详细内容
bash
# 1. 先用 DuckDuckGo 搜索
python -c "
from duckduckgo_search import DDGS
with DDGS() as ddgs:
results = list(ddgs.text('Python async tutorial', max_results=1))
if results:
url = results[0]['href']
print(f'URL: {url}')
"
# 2. 用 browser-use 打开并获取详细内容
browser-use open <url_from_search>
browser-use state
注意事项
⚠️ 使用建议：
- 遵守使用频率限制：避免短时间内大量请求
- 合理设置结果数量：不要一次请求过多结果
- 添加适当延迟：批量搜索时在请求之间添加
time.sleep() - 处理异常情况：始终添加错误处理代码
- 尊重版权：搜索结果仅供参考，注意内容版权
