└─────────────────────────────────────────────────────────────┘
|
||
```
|
||
|
||
### Core Components
|
||
|
||
#### 1. ChatSearch.svelte - Main Component
|
||
**Location**: `src/lib/components/chat/ChatSearch.svelte`
|
||
|
||
```typescript
|
||
// Core Props & State
|
||
export let show = false;
|
||
export let history = { messages: {}, currentId: null };
|
||
|
||
let searchQuery = '';
|
||
let matchingMessageIds: string[] = [];
|
||
let currentIndex = 0;
|
||
let isNavigating = false;
|
||
|
||
// Computed Values
|
||
$: totalResults = matchingMessageIds.length;
|
||
$: currentResult = totalResults > 0 ? currentIndex + 1 : 0;
|
||
$: if (show && searchInput) searchInput.focus();
|
||
```
|
||
|
||
**Key Features**:
|
||
- Real-time search with `on:input` event handling
|
||
- DOM TreeWalker for efficient text node traversal
|
||
- CSS class-based highlighting system
|
||
- Smooth scroll navigation with `scrollIntoView`
|
||
- Click-outside detection for UX
|
||
|
||
#### 2. Global State Management
|
||
**Location**: `src/lib/stores/index.ts`
|
||
|
||
```typescript
|
||
// Following existing Open WebUI patterns
|
||
export const showChatSearch: Writable<boolean> = writable(false);
|
||
```
|
||
|
||
**Pattern Consistency**:
|
||
- Matches existing `showSearch`, `showSidebar` store patterns
|
||
- Global state accessible across components
|
||
- Clean separation of concerns
|
||
|
||
#### 3. Keyboard Handler Integration
|
||
**Location**: `src/routes/(app)/+layout.svelte`
|
||
|
||
```typescript
|
||
const handleKeyDown = (event: KeyboardEvent) => {
|
||
if (event.ctrlKey && event.key === 'f' && $page.route.id?.includes('chat')) {
|
||
event.preventDefault();
|
||
showChatSearch.set(true);
|
||
}
|
||
};
|
||
```
|
||
|
||
**Smart Activation**:
|
||
- Only activates on chat pages (`route.id?.includes('chat')`)
|
||
- Prevents interference with browser's native Ctrl+F
|
||
- Global keyboard event handling
|
||
|
||
#### 4. Chat Integration
|
||
**Location**: `src/lib/components/chat/Chat.svelte`
|
||
|
||
```svelte
|
||
<!-- Seamless integration with existing chat UI -->
|
||
{#if $showChatSearch}
|
||
<ChatSearch
|
||
bind:show={$showChatSearch}
|
||
{history}
|
||
on:close={() => showChatSearch.set(false)}
|
||
/>
|
||
{/if}
|
||
```
|
||
|
||
### Search Algorithm Deep Dive
|
||
|
||
#### Text Matching Strategy
|
||
```typescript
|
||
const performSearch = (query: string) => {
|
||
const searchTerm = query.toLowerCase().trim();
|
||
const messageResults: Array<{id: string, timestamp: number}> = [];
|
||
|
||
// Iterate through all messages
|
||
Object.values(history.messages).forEach((message: any) => {
|
||
if (message?.content && typeof message.content === 'string') {
|
||
if (message.content.toLowerCase().includes(searchTerm)) {
|
||
messageResults.push({
|
||
id: message.id,
|
||
timestamp: message.timestamp || 0
|
||
});
|
||
}
|
||
}
|
||
});
|
||
|
||
// Sort chronologically (top to bottom)
|
||
messageResults.sort((a, b) => a.timestamp - b.timestamp);
|
||
matchingMessageIds = messageResults.map(result => result.id);
|
||
};
|
||
```
|
||
|
||
**Algorithm Features**:
|
||
- **Case-insensitive matching** for user-friendly search
|
||
- **Timestamp-based ordering** for chronological navigation
|
||
- **Content validation** to handle various message types
|
||
- **Efficient filtering** with early returns
|
||
|
||
#### Highlighting Implementation
|
||
```typescript
|
||
const highlightInElement = (element: Element, searchTerm: string) => {
|
||
const walker = document.createTreeWalker(
|
||
element,
|
||
NodeFilter.SHOW_TEXT,
|
||
{
|
||
acceptNode: (node) => {
|
||
const parent = node.parentElement;
|
||
if (!parent || parent.classList.contains('search-highlight') ||
|
||
parent.tagName === 'SCRIPT' || parent.tagName === 'STYLE') {
|
||
return NodeFilter.FILTER_REJECT;
|
||
}
|
||
return NodeFilter.FILTER_ACCEPT;
|
||
}
|
||
}
|
||
);
|
||
|
||
// Process text nodes and create highlighted spans
|
||
textNodes.forEach(textNode => {
|
||
// Create document fragment with highlighted content
|
||
const fragment = document.createDocumentFragment();
|
||
// ... highlighting logic
|
||
parent.replaceChild(fragment, textNode);
|
||
});
|
||
};
|
||
```
|
||
|
||
**Highlighting Features**:
|
||
- **DOM TreeWalker** for efficient text node traversal
|
||
- **Fragment-based replacement** for performance
|
||
- **CSS class-based styling** for consistent appearance
|
||
- **Script/Style tag filtering** to avoid breaking functionality
|
||
|
||
### Performance Optimizations
|
||
|
||
#### 1. Efficient DOM Operations
|
||
```typescript
|
||
// Constants for CSS classes (no duplication)
|
||
const HIGHLIGHT_CLASS = 'search-highlight bg-yellow-200 dark:bg-yellow-600 px-0.5 rounded underline';
|
||
const HIGHLIGHT_BLUE_CLASS = 'search-highlight bg-blue-200 dark:bg-blue-600 px-0.5 rounded underline';
|
||
|
||
// Batch DOM operations
|
||
const clearHighlights = () => {
|
||
const highlights = document.querySelectorAll('.search-highlight');
|
||
highlights.forEach(highlight => {
|
||
const parent = highlight.parentNode;
|
||
if (parent) {
|
||
parent.replaceChild(document.createTextNode(highlight.textContent || ''), highlight);
|
||
parent.normalize(); // Merge adjacent text nodes
|
||
}
|
||
});
|
||
};
|
||
```
|
||
|
||
#### 2. Memory Management
|
||
```typescript
|
||
onDestroy(() => {
|
||
clearHighlights(); // Clean up DOM modifications
|
||
document.removeEventListener('click', handleClickOutside);
|
||
});
|
||
```
|
||
|
||
#### 3. Event Optimization
|
||
```typescript
|
||
// Debounced search with on:input (not reactive statements)
|
||
const handleInput = () => {
|
||
performSearch(searchQuery); // Explicit user-triggered execution
|
||
};
|
||
```
|
||
|
||
## 🎨 UI/UX Design Principles
|
||
|
||
### Design Philosophy
|
||

|
||
```css
|
||
/* Search Container */
|
||
.search-container {
|
||
@apply fixed top-4 right-4 z-50 bg-white dark:bg-gray-800
|
||
rounded-lg shadow-lg border border-gray-200 dark:border-gray-700
|
||
p-3 w-80;
|
||
}
|
||
|
||
/* Highlighting Styles */
|
||
.search-highlight {
|
||
@apply bg-yellow-200 dark:bg-yellow-600 px-0.5 rounded underline;
|
||
}
|
||
|
||
/* Navigation Feedback */
|
