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]}...\")

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：

1. 遵守使用频率限制：避免短时间内大量请求
2. 合理设置结果数量：不要一次请求过多结果
3. 添加适当延迟：批量搜索时在请求之间添加 time.sleep()
4. 处理异常情况：始终添加错误处理代码
5. 尊重版权：搜索结果仅供参考，注意内容版权
