Troubleshooting Guide - Module 8: Search Explorer & Portal Tools¶

This guide helps you diagnose and resolve common issues when working with Azure AI Search portal tools, including Search Explorer, Import Data wizard, and portal management features.

Search Explorer Issues¶

1. Cannot Access Search Explorer¶

Symptoms: - Search Explorer option not visible in portal - "Access denied" error when trying to open Search Explorer - Search Explorer loads but shows no indexes

Common Causes and Solutions:

Missing Permissions¶

Cause: Insufficient permissions to access search service Solution: 1. Verify you have appropriate role assignments: - Search Service Contributor (for full access) - Search Index Data Reader (for query access) 2. Check with your Azure administrator for proper permissions 3. Ensure you're accessing the correct subscription and resource group

Service Not Found¶

Cause: Search service doesn't exist or is in different subscription Solution: 1. Verify search service name and location 2. Check you're in the correct subscription 3. Confirm service is running and not deleted

Browser Issues¶

Cause: Browser cache or compatibility issues Solution:

# Clear browser cache and cookies
# Try incognito/private browsing mode
# Use supported browsers: Chrome, Firefox, Safari, Edge

2. Query Syntax Errors in Search Explorer¶

Error Message:

Invalid expression: Syntax error at position X in 'query expression'

Common Syntax Issues:

Incorrect Filter Syntax¶

// ❌ Wrong: Using SQL-style operators
{
  "search": "hotel",
  "filter": "Rating > 4.0"
}

// ✅ Correct: Using OData operators
{
  "search": "hotel",
  "filter": "Rating gt 4.0"
}

Missing Quotes in String Filters¶

// ❌ Wrong: Missing quotes around string values
{
  "search": "*",
  "filter": "Category eq Luxury"
}

// ✅ Correct: Proper string quoting
{
  "search": "*",
  "filter": "Category eq 'Luxury'"
}

Invalid Field References¶

// ❌ Wrong: Case-sensitive field name error
{
  "search": "hotel",
  "filter": "rating gt 4.0"
}

// ✅ Correct: Exact field name match
{
  "search": "hotel",
  "filter": "Rating gt 4.0"
}

Malformed JSON¶

// ❌ Wrong: Invalid JSON structure
{
  "search": "hotel",
  "filter": "Rating gt 4.0",  // Extra comma
}

// ✅ Correct: Valid JSON
{
  "search": "hotel",
  "filter": "Rating gt 4.0"
}

3. No Search Results Returned¶

Symptoms: - Query executes successfully but returns zero results - Expected documents are not appearing in results - Facets show no values

Diagnostic Steps:

Check Index Content¶

// Test if index has any documents
{
  "search": "*",
  "top": 1
}

Verify Field Configuration¶

// Check if fields are searchable
{
  "search": "hotel",
  "searchFields": "HotelName"  // Ensure field is searchable
}

Test with Broader Queries¶

// Start with wildcard search
{
  "search": "*"
}

// Then narrow down
{
  "search": "hotel"
}

Check Filter Logic¶

// Test without filters first
{
  "search": "hotel"
}

// Then add filters incrementally
{
  "search": "hotel",
  "filter": "Rating gt 0"  // Very broad filter
}

4. Search Explorer Performance Issues¶

Symptoms: - Queries taking longer than expected - Browser timeouts - Slow response times

Solutions:

Limit Result Set Size¶

// ✅ Good: Reasonable result size
{
  "search": "*",
  "top": 20
}

// ❌ Avoid: Large result sets
{
  "search": "*",
  "top": 1000
}

Use Field Selection¶

// ✅ Good: Select only needed fields
{
  "search": "hotel",
  "select": "HotelName,Rating"
}

// ❌ Avoid: Returning all fields
{
  "search": "hotel"
}

Optimize Filter Order¶

// ✅ Good: Most selective filter first
{
  "search": "*",
  "filter": "Category eq 'Luxury' and Rating gt 4.0"
}

// ❌ Less efficient: Less selective filter first
{
  "search": "*",
  "filter": "Rating gt 0 and Category eq 'Luxury'"
}
