# 🔍 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);
 | 
						|
```
 | 
						|
 | 
						|

 | 
						|
✅ 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
 | 
						|
```
 | 
						|
 | 
						|
