ALPHA_VANTAGE_KEY = "your_alphavantage_key"
AV_BASE_URL = "https://www.alphavantage.co/query"
```

#### API调用示例
```python
import requests
import feedparser
from datetime import datetime

class SimpleSearchEngine:
    def __init__(self):
        self.news_api_key = "YOUR_KEY"
        self.rss_sources = {

    def search_by_industry(self, keywords, industry, language="en"):
        results = []
        
        # RSS搜索
        for rss_url in self.rss_sources.get(industry, []):
            feed = feedparser.parse(rss_url)
            for entry in feed.entries:
                if any(keyword.lower() in entry.title.lower() for keyword in keywords):
                    results.append({
