# 🔍 PR: Fix & Complete ObsiViewer Search (Obsidian Parity)
|
|
|
|
## 📋 Summary
|
|
|
|
This PR fixes and completes the ObsiViewer search implementation to achieve **full parity with Obsidian**. All field operators now work correctly, highlighting is robust, and UI options (Collapse results, Show more context) are fully functional.
|
|
|
|
## 🎯 Problem Statement
|
|
|
|
The existing search implementation had critical issues:
|
|
|
|
1. **Broken filter pipeline**: Field operators (`file:`, `path:`, `tag:`, etc.) were parsed but **not applied** to results
|
|
2. **Incomplete highlighting**: Basic text matching without precise ranges
|
|
3. **Missing UI features**: No "Collapse results" or "Show more context" toggles
|
|
4. **Desynchronized search bars**: Header and sidebar used different pipelines
|
|
|
|
## ✅ Solution
|
|
|
|
### Core Architecture Changes
|
|
|
|
#### 1. New `SearchOrchestratorService` (Unified Pipeline)
|
|
- **Before**: Parser → Evaluator (ignored predicate) → Basic keyword matching
|
|
- **After**: Parser → Orchestrator → Predicate filtering → Range extraction → Highlighting
|
|
|
|
```typescript
|
|
// NEW: All operators are now actually applied
|
|
const results = orchestrator.execute('file:readme.md tag:#work', options);
|
|
// Returns ONLY files named readme.md with #work tag
|
|
```
|
|
|
|
#### 2. New `SearchHighlighterService` (Robust Highlighting)
|
|
- Precise `MatchRange` with start/end/line/context
|
|
- XSS protection (HTML escape)
|
|
- Support for case sensitivity, regex, wildcards
|
|
|
|
```typescript
|
|
// Highlights using pre-calculated ranges (no rescanning)
|
|
const html = highlighter.highlightWithRanges(text, match.ranges);
|
|
```
|
|
|
|
#### 3. New `SearchPreferencesService` (Persistent UI State)
|
|
- Per-context preferences (vault/header/graph)
|
|
- localStorage persistence
|
|
- Toggles: `collapseResults`, `showMoreContext`, `explainSearchTerms`
|
|
|
|
```typescript
|
|
// Preferences survive page reload
|
|
preferences.updatePreferences('vault', { collapseResults: true });
|
|
```
|
|
|
|
### UI Enhancements
|
|
|
|
#### Search Panel (Updated)
|
|
- ✅ **Collapse results** toggle (matches Image 4)
|
|
- ✅ **Show more context** toggle (2 vs 5 lines, matches Image 5)
|
|
- ✅ **Explain search terms** toggle (hook for future)
|
|
- ✅ iOS-style toggle switches
|
|
- ✅ Preferences auto-load on init
|
|
|
|
#### Search Results (Updated)
|
|
- ✅ Accepts `collapseAll`, `showMoreContext`, `contextLines` inputs
|
|
- ✅ Uses `SearchHighlighterService` for precise highlighting
|
|
- ✅ Reacts to preference changes with Angular `effect()`
|
|
|
|
### Backward Compatibility
|
|
|
|
`SearchEvaluatorService` remains functional as a **legacy wrapper**:
|
|
|
|
```typescript
|
|
// Old code still works (delegates to orchestrator)
|
|
const results = searchEvaluator.search(query, options);
|
|
|
|
// New code (recommended)
|
|
const results = orchestrator.execute(query, options);
|
|
```
|
|
|
|

## 🧪 Test Coverage
|
|
|
|
### Unit Tests (New)
|
|
- **Orchestrator**: 15+ tests covering all operators
|
|
- **Highlighter**: 12+ tests covering highlighting, snippets, XSS
|
|
|
|
### E2E Tests (New)
|
|
- 20+ Playwright scenarios
|
|
- Coverage: operators, toggles, highlighting, persistence
|
|
|
|
### Example Test Cases
|
|
```typescript
|
|
✅ file:.jpg → filters by filename
|
|
✅ path:"Daily notes" → filters by path
|
|
✅ tag:#work → filters by tag
|
|
✅ [status]:"draft" → filters by property
|
|
✅ task-todo:review → filters incomplete tasks
|
|
✅ (Python OR JavaScript) -deprecated → boolean logic
|
|
✅ Collapse toggle → groups collapse/expand
|
|
✅ Show more context → snippets extend
|
|
✅ Preferences persist after reload
|
|
```
|
|
|
|
## 🎨 Visual Validation
|
|
|
|
The implementation matches the provided screenshots:
|
|
|
|
| Screenshot | Feature | Status |
|
|
|------------|---------|--------|
|
|
| Image 1 | Search options panel | ✅ Matches |
|
|
| Image 2 | Results with highlights | ✅ Matches |
|
|
| Image 3 | Toggles OFF | ✅ Matches |
|
