/**
 * Test script to verify that relevance scores are properly affecting search results
 * 
 * This script:
 * 1. Creates a test zone with entities of varying relevance scores
 * 2. Performs searches with different sort orders
 * 3. Checks if sorting by importance returns entities in the correct order
 * 4. Tests if the AI filtering and automatic relevance score updating works
