# Tokenize text
text = "Hello world!"
tokens = all_tokenizations(text)

# Get word tokens
word_tokens = tokens["word"]
print(f"Word tokens: {[t['text'] for t in word_tokens]}")

# Calculate numerology
for token in word_tokens:
    digit = numerology_sum(token['text'])
    print(f"'{token['text']}' -> {digit}")
```

### Advanced Processing with Concurrency
```python
from SanTOK import ConcurrentTokenProcessor, AsyncTokenProcessor

# Concurrent processing
processor = ConcurrentTokenProcessor(max_workers=4, chunk_size=1000)
results = processor.process_text_concurrent(text, ["word", "char", "space"])

# Async processing
async def process_async():
    async_processor = AsyncTokenProcessor(max_concurrent_tasks=5)
    results = await async_processor.process_texts_async([text1, text2, text3])
    return results
```

### Text Analysis
```python
from SanTOK import find_similar_tokens, find_token_patterns, detect_token_anomalies

# Tokenize first
tokenizer = SanTOKTokenizer(seed=12345, embedding_bit=True)
streams = tokenizer.build("Your text here")
tokens = streams["word"].tokens

# Similarity analysis
similar_groups = find_similar_tokens(tokens, similarity_threshold=0.7)

# Pattern recognition
patterns = find_token_patterns(tokens, min_pattern_length=2, max_pattern_length=4)
