Quickwit Search

Quickwit Search Skill

Search log and observability data using Quickwit search engine integration for Terraphim AI.

When to Use

• Searching application logs for errors, warnings, or specific patterns
• Investigating production incidents and debugging issues
• Analyzing observability data across multiple indexes
• Correlating log entries with code changes or deployments
• Exploring log data without knowing exact index names

Features

• Hybrid Index Discovery - Explicit configuration or auto-discovery
• Dual Authentication - Bearer token and Basic Auth support
• Pattern Filtering - Glob patterns like logs-*, *-workers
• Multi-Index Search - Search across multiple log indexes simultaneously
• Time-Sorted Results - Most recent logs first by default

Quick Start

Basic Search (Explicit Index)

# Configure Quickwit haystack
export QUICKWIT_CONFIG='{
  "location": "http://localhost:7280",
  "service": "Quickwit",
  "extra_parameters": {
    "default_index": "workers-logs"
  }
}'

# Search for errors
terraphim-agent --config quickwit_engineer_config.json
> /search error

Auto-Discovery Mode

# Search all available indexes
terraphim-agent --config quickwit_autodiscovery_config.json
> /search "level:ERROR"

Filtered Discovery

# Search only indexes matching pattern
terraphim-agent --config quickwit_production_config.json  # with index_filter: "workers-*"
> /search "database connection failed"

Configuration Modes

Mode 1: Explicit Index (Fast - Recommended for Production)

Use When:

• You know the exact index name
• Performance is critical
• Production monitoring

Configuration:

{
  "name": "Quickwit Production Monitor",
  "haystacks": [
    {
      "location": "http://localhost:7280",
      "service": "Quickwit",
      "extra_parameters": {
        "default_index": "workers-logs",
        "max_hits": "100"
      }
    }
  ]
}

Performance: ~100-200ms per search (1 API call)

Mode 2: Auto-Discovery (Convenient - Recommended for Exploration)

Use When:

• Exploring unfamiliar Quickwit instance
• Don't know available index names
• Want comprehensive search across all logs

Configuration:

{
  "name": "Quickwit Explorer",
  "haystacks": [
    {
      "location": "http://localhost:7280",
      "service": "Quickwit",
      "extra_parameters": {
        "max_hits": "50"
      }
    }
  ]
}

Performance: ~300-500ms per search (N+1 API calls for N indexes)

Mode 3: Filtered Discovery (Balanced)

Use When:

• Want convenience of auto-discovery
• Need to limit scope to specific indexes
• Multi-tenant or multi-service environments

Configuration:

{
  "name": "Quickwit Service Monitor",
  "haystacks": [
    {
      "location": "http://localhost:7280",
      "service": "Quickwit",
      "extra_parameters": {
        "index_filter": "workers-*",
        "max_hits": "100"
      }
    }
  ]
}

Glob Patterns:

• workers-* - Matches: workers-logs, workers-metrics
• *-logs - Matches: api-logs, service-logs, workers-logs
• *logs* - Matches any index containing "logs"
• * - Matches all indexes (same as auto-discovery)

Performance: ~200-400ms per search (depends on matching indexes)

Authentication

Bearer Token

For API token-based authentication:

{
  "extra_parameters": {
    "auth_token": "Bearer your-api-token-here",
    "default_index": "logs"
  }
}

Security: Store token in environment variable:

export QUICKWIT_TOKEN="Bearer $(cat ~/.quickwit/token)"
# Update config to use ${QUICKWIT_TOKEN}

Basic Authentication

Secure Password Management:

# Using 1Password CLI
export QUICKWIT_PASSWORD=$(op read "op://Private/Quickwit/password")

# Or use existing environment variable if set
# export QUICKWIT_PASSWORD

# Then start terraphim-agent
terraphim-agent --config quickwit_production_config.json

Query Syntax

Quickwit supports powerful query syntax:

Simple Text Search

/search error
/search "database connection"
/search timeout

Field-Specific Search

/search "level:ERROR"
/search "service:api-server"
/search "message:database"

Boolean Operators

/search "error AND database"
/search "error OR timeout"
/search "level:ERROR AND service:api"

Range Queries

/search "timestamp:[2024-01-01 TO 2024-01-31]"
/search "level:ERROR AND timestamp:[2024-01-13T00:00:00Z TO *]"

Complex Queries

/search "level:ERROR AND (message:database OR message:connection)"
/search "service:api-server AND NOT level:INFO"

Configuration Parameters

Usage Examples

Example 1: Debug Production Error

terraphim-agent --config quickwit_engineer_config.json

# In REPL:
/search "level:ERROR AND timestamp:[2024-01-13T10:00:00Z TO *]"
/search "message:NullPointerException"
/search "service:payment-processor AND level:ERROR"

Example 2: Incident Investigation

# Search across all service logs
terraphim-agent --config quickwit_autodiscovery_config.json

# Find all errors around incident time
/search "timestamp:[2024-01-13T09:50:00Z TO 2024-01-13T10:10:00Z]"

# Correlate with specific service
/search "service:api-gateway AND (error OR timeout OR 5**)"

Example 3: Performance Analysis

# Search for slow queries
/search "message:slow AND level:WARN"

# Find timeout patterns
/search "timeout OR timed_out OR deadline_exceeded"

# Analyze specific endpoint
/search "path:/api/users AND (slow OR error)"

Example 4: Multi-Service Correlation

Configure multiple Quickwit haystacks for different services:

{
  "name": "Multi-Service Monitor",
  "haystacks": [
    {
      "location": "http://localhost:7280",
      "service": "Quickwit",
      "extra_parameters": {
        "default_index": "api-logs"
      }
    },
    {
      "location": "http://localhost:7280",
      "service": "Quickwit",
      "extra_parameters": {
        "default_index": "worker-logs"
      }
    }
  ]
}

Then search returns results from both indexes unified.

Troubleshooting

Connection Issues

Problem: "Failed to connect to Quickwit"

Solutions:

1. Verify Quickwit is running:

   curl http://localhost:7280/health
   

2. Check firewall/network connectivity
3. Verify URL in configuration

Authentication Failures

Problem: Status 401 or 403

Solutions:

1. Verify credentials are correct
2. Check Bearer token includes "Bearer " prefix
3. Test auth with curl:

   curl -H "Authorization: Bearer token" http://localhost:7280/api/v1/indexes
   

No Results

Problem: Search returns empty

Possible Causes:

1. Index is empty - verify:

   curl "http://localhost:7280/api/v1/workers-logs/search?query=*&max_hits=10"
   

2. Query doesn't match any logs - try broader query
3. Auto-discovery found no indexes - check logs for warnings

Auto-Discovery Not Working

Problem: "No indexes discovered"

Solutions:

1. Test endpoint directly:

   curl http://localhost:7280/api/v1/indexes
   

2. Check authentication if required
3. Use explicit default_index as workaround

Performance Tips

For Fast Searches

• Use explicit default_index (avoids discovery overhead)
• Reduce max_hits to minimum needed
• Use specific field queries: level:ERROR faster than text search

For Comprehensive Searches

• Use auto-discovery or index_filter: "*"
• Increase max_hits if needed
• Combine with time ranges to limit scope

Integration with Other Haystacks

Quickwit works alongside other Terraphim haystacks:

{
  "haystacks": [
    {
      "location": "/path/to/docs",
      "service": "Ripgrep"
    },
    {
      "location": "http://localhost:7280",
      "service": "Quickwit",
      "extra_parameters": {
        "index_filter": "logs-*"
      }
    }
  ]
}

Search query returns unified results from both code/docs and logs.

Docker Setup for Testing

# docker-compose.yml
version: '3.8'
services:
  quickwit:
    image: quickwit/quickwit:0.7
    ports:
      - "7280:7280"
    command: ["quickwit", "run", "--service", "searcher"]
    volumes:
      - ./quickwit-data:/quickwit/qwdata

Start Quickwit:

docker-compose up -d
curl http://localhost:7280/health

Best Practices

1. Production: Use explicit index configuration for predictable performance
2. Development: Use auto-discovery for exploration and debugging
3. Security: Store credentials in environment variables or 1Password
4. Performance: Limit max_hits and use specific queries
5. Monitoring: Watch terraphim-agent logs for Quickwit connectivity warnings
