## 🔍 What It Does

### Before
```
Toggle: [☑ Use metadata filter]
Input:  [🔍 {"category": "ML"}                    ]
```

### After
```
Toggle: [☑ Use metadata filter]

┌─────────────────────────────────────────────────┐
│ 🔍 Filter Builder    [Show JSON] [+ Add]       │
├─────────────────────────────────────────────────┤
│     [category▼] [Equals▼] [ML      ] [🗑]     │
│ AND [price   ▼] [< Less▼] [100     ] [🗑]     │
├─────────────────────────────────────────────────┤
│ Generated JSON:                                 │
│ {                                               │
│   "category": "ML",                             │
│   "price": { "$lt": 100 }                       │
│ }                                               │
└─────────────────────────────────────────────────┘
```

## ✨ Features

1. **Visual Construction** - No JSON syntax knowledge needed
2. **8 Operators** - Covers all common filter scenarios
3. **Smart Types** - Auto-detects numbers vs strings
4. **AND Logic** - Multiple conditions combine with AND
5. **Range Merging** - Multiple conditions on same field merge
6. **JSON Preview** - Toggle to see generated filter
7. **Empty State** - Helpful message when no conditions
8. **Dark Theme** - Matches existing dashboard
9. **Responsive** - Works on all screen sizes
10. **Accessible** - Keyboard navigation, proper labels

## 📊 Filter Capabilities

### Operators Supported

| Operator | Symbol | Example | JSON Output |
|----------|--------|---------|-------------|
| Equals | = | category = ML | `{ "category": "ML" }` |
| Not Equals | ≠ | status ≠ active | `{ "status": { "$ne": "active" }}` |
| Greater Than | > | price > 50 | `{ "price": { "$gt": 50 }}` |
| Less Than | < | age < 30 | `{ "age": { "$lt": 30 }}` |
| Greater or Equal | ≥ | score ≥ 0.8 | `{ "score": { "$gte": 0.8 }}` |
| Less or Equal | ≤ | quantity ≤ 100 | `{ "quantity": { "$lte": 100 }}` |
| Contains | ⊃ | tags ⊃ ai | `{ "tags": { "$contains": "ai" }}` |
| Exists | ∃ | metadata ∃ true | `{ "metadata": { "$exists": true }}` |

### Use Cases

1. **Category Filtering** - Find vectors by category
2. **Range Queries** - Price between X and Y
3. **Multi-Field** - Category AND tags AND score
4. **Existence Checks** - Has certain metadata field
5. **String Matching** - Contains specific text
6. **Numeric Comparisons** - Greater than, less than thresholds

## 🧪 Testing

### Quick Test
1. `npm run dev`
2. Toggle "Use metadata filter" ON
3. Click "+ Add Condition"
4. Set: `category` = `ML`
5. Click "Show JSON" → Should see `{ "category": "ML" }`
6. Search → Filter applied

### Full Test
- [ ] Add single condition
- [ ] Add multiple conditions
- [ ] Remove condition
- [ ] Toggle JSON preview
- [ ] Change operators
- [ ] Test numeric values
- [ ] Test string values
- [ ] Test exists operator
- [ ] Verify search applies filter
- [ ] Check empty state message
