πŸ”§ Troubleshooting

Common Issues

Issue: IndexError: BloomFilter is at capacity

# Solution: Increase Bloom filter capacity
# Edit advanced_app.py line 310:
self.bloom_filter = BloomFilter(capacity=200000, error_rate=0.01)

Issue: ModuleNotFoundError: No module named 'pybloom_live'

pip install pybloom-live

Issue: sqlite3.OperationalError: database is locked

# Close all database connections
# Restart the application
streamlit run advanced_app.py

Issue: Slow performance with large dictionary

# Optimize database
python check_db.py
# Consider using PostgreSQL for production

Performance Optimization

  1. Increase Bloom Filter Capacity

    self.bloom_filter = BloomFilter(capacity=200000, error_rate=0.01)
  2. Enable Database Indexing

    CREATE INDEX idx_words_word ON words(word);
    CREATE INDEX idx_words_category ON words(category);
  3. Use Caching

    from functools import lru_cache
    
    @lru_cache(maxsize=1000)
    def get_suggestions_cached(prefix, algorithm):
        return system.get_suggestions(prefix, algorithm)
