# Work Summary: Execution Search Enhancement
**Date**: 2026-01-18  
**Session**: 7 (continued)  
**Status**: ✅ Complete

## Overview

Enhanced the execution search capabilities in both the API and CLI to support filtering by pack name and searching within execution results. This makes it much easier for users to find specific executions based on their output or organizational structure.

## Objectives

- Add pack-based filtering for executions
- Enable searching within execution result JSON
- Maintain backward compatibility with existing API
- Update CLI with new filter options
- Document new capabilities

## Implementation Details

### API Changes

#### 1. Updated ExecutionQueryParams (`crates/api/src/dto/execution.rs`)

Added two new optional query parameters:

```rust
pub struct ExecutionQueryParams {
    // ... existing fields ...
    
    /// Filter by pack name
    #[param(example = "core")]
    pub pack_name: Option<String>,

    /// Search in result JSON (case-insensitive substring match)
    #[param(example = "error")]
    pub result_contains: Option<String>,
    
    // ... other fields ...
}
```

#### 2. Updated list_executions Handler (`crates/api/src/routes/executions.rs`)

Added filtering logic:

**Pack Name Filter:**
```rust
if let Some(pack_name) = &query.pack_name {
    filtered_executions.retain(|e| {
        // action_ref format is "pack.action"
        e.action_ref.starts_with(&format!("{}.", pack_name))
    });
}
```

**Result Search Filter:**
```rust
if let Some(result_search) = &query.result_contains {
    let search_lower = result_search.to_lowercase();
    filtered_executions.retain(|e| {
        if let Some(result) = &e.result {
            // Convert result to JSON string and search case-insensitively
            let result_str = serde_json::to_string(result).unwrap_or_default();
            result_str.to_lowercase().contains(&search_lower)
        } else {
            false
        }
    });
}
```

### CLI Changes

#### 1. Updated Execution List Command (`crates/cli/src/commands/execution.rs`)

Added new command-line options:

```rust
List {
    /// Filter by pack name
    #[arg(short, long)]
    pack: Option<String>,

    /// Filter by action name
    #[arg(short, long)]
    action: Option<String>,

    /// Filter by status
    #[arg(short, long)]
    status: Option<String>,

    /// Search in execution result (case-insensitive)
    #[arg(short, long)]
    result: Option<String>,

    /// Limit number of results
    #[arg(short, long, default_value = "50")]
    limit: i32,
}
```

#### 2. Updated Query String Building

Fixed and enhanced query parameter construction:
- Changed `limit` to `per_page` to match API
- Changed `action` to `action_ref` to match API
- Added URL encoding for search terms
- Added new pack_name and result_contains parameters

#### 3. Added URL Encoding Dependency

Added `urlencoding = "2.1"` to properly encode query parameters with special characters.

### Usage Examples

#### CLI Usage

```bash
# Filter by pack
attune execution list --pack core

# Filter by action within pack
attune execution list --pack monitoring --action health_check

# Search in results
attune execution list --result "error"
attune execution list --result "timeout"

# Combine multiple filters
attune execution list --pack monitoring --status failed --result "connection refused"

# With limit
attune execution list --pack core --status succeeded --limit 100
```

#### API Usage

```bash
# Filter by pack
curl "http://localhost:8080/api/v1/executions?pack_name=core"

# Search in results
curl "http://localhost:8080/api/v1/executions?result_contains=error"

# Combine filters
curl "http://localhost:8080/api/v1/executions?pack_name=monitoring&status=failed&result_contains=timeout"
```

#### Scripting Example

```bash
#!/bin/bash
# Find all failed monitoring executions with timeout errors

attune execution list \
  --pack monitoring \
  --status failed \
  --result timeout \
  --output json | \
  jq -r '.[] | "\(.id): \(.action_name) - \(.created)"'
```

## Use Cases

### 1. Troubleshooting Pack Issues
Quickly find all failed executions from a specific pack:
```bash
attune execution list --pack monitoring --status failed
```

### 2. Error Pattern Analysis
Search for specific error messages across all executions:
```bash
attune execution list --result "connection refused"
attune execution list --result "timeout"
```

### 3. Pack-Specific Monitoring
Monitor execution results for a specific pack:
```bash
attune execution list --pack core --limit 100 --output json | \
  jq '[.[] | {id, status, result}]'
```

### 4. Debugging Workflows
Find executions with specific result patterns:
```bash
attune execution list --result "workflow_step_3" --status failed
```

## Technical Details

### Pack Name Extraction

Pack names are extracted from the `action_ref` field which follows the format `pack_name.action_name`:
- `core.echo` → pack: `core`
- `monitoring.health_check` → pack: `monitoring`

The filter uses `starts_with()` to match the pack prefix efficiently.

### Result Search Implementation

Result searching is case-insensitive and performs substring matching:
1. Convert result JSON to string representation
2. Convert both search term and result to lowercase
3. Check if result contains the search term

**Important Notes:**
- Searches the entire JSON structure (keys and values)
- Case-insensitive for user convenience
- Returns false if execution has no result

### Query Parameter Alignment

Fixed inconsistencies between CLI and API:
- CLI `--action` → API `action_ref`
- CLI `--limit` → API `per_page`
- Added URL encoding for special characters

## Testing

### Manual Testing

```bash
# Build and test
cargo build -p attune-cli
cargo check -p attune-api

# Test help text
./target/debug/attune execution list --help

# Verify new options appear
# - Should show --pack option
# - Should show --result option
```

2. **Pack Debugging**: Isolate issues to specific packs
3. **Pattern Detection**: Identify recurring error patterns
4. **Audit Trail**: Search executions by result content

## Performance Considerations

Current implementation:
- Filtering happens in-memory after database query
- Suitable for current scale
- May need optimization for large datasets

Future optimizations could include:
1. Database-level JSON search (PostgreSQL JSONB operators)
2. Full-text search indexing for results
3. Caching for common pack filters
4. Query result streaming for large datasets

## Future Enhancements

Potential improvements:
1. **Advanced JSON Querying**: Use JSONPath or JQ-like syntax
2. **Result Field Filtering**: Search specific fields only
3. **Regular Expression Support**: More powerful pattern matching
4. **Date Range Filtering**: Filter by execution time
5. **Duration Filtering**: Find long-running executions
6. **Parent/Child Filtering**: Search workflow hierarchies
7. **Tag-Based Search**: If tags are added to executions
