console.log('✅ Consolidated API Tests Complete!')
console.log('Key improvements:')
console.log('  • search() now handles all vector search cases')
console.log('  • find() handles natural language and complex queries')
console.log('  • Both support pagination (offset & cursor)')
console.log('  • Metadata filtering with O(log n) performance')
console.log('  • Soft deletes filtered by default')
console.log('  • Maximum 10,000 results for safety')
