import { SearchModal, SearchResultCard, SearchHistory } from '@/components/search'

function MySearchPage() {
  const [results, setResults] = useState([])

  return (
    <div>
      <SearchModal
        onSearch={(query) => performSearch(query)}
        onMessageClick={(result) => openMessage(result)}
      />

      <div className="results">
        {results.map((result) => (
          <SearchResultCard key={result.id} result={result} onClick={openMessage} />
        ))}
      </div>
    </div>
  )
}

import { AdvancedSearchBuilder, SearchFilters } from '@/components/search'

function AdvancedSearchPage() {
  return (
    <div>
      <AdvancedSearchBuilder
        onChange={(query, parts) => {
          console.log('Built query:', query)
          console.log('Query parts:', parts)
        }}
        onSearch={performSearch}
      />
    </div>
  )
}

import { SearchAnalytics } from '@/components/admin/search'

function AdminDashboard() {
  return (
    <SearchAnalytics
      timeRange="month"
      onExport={(data) => {
        // Export as CSV or JSON
        downloadFile(data, 'analytics.json')
      }}
    />
  )
}

All search components support keyboard navigation:

• Cmd/Ctrl + K - Open search modal
• Cmd/Ctrl + Shift + K - Open search with filters

• Enter - Select result
• Tab - Switch between tabs

All components are mobile-responsive:

• Touch-friendly targets (minimum 44px)
• Swipe gestures for navigation
• Simplified layouts on small screens
• Progressive disclosure of advanced features

All components support data export:

1. Search History: Export as JSON
2. Saved Searches: Export/import with categories
3. Search Analytics: Export as JSON or CSV
4. Query Builder: Export/import query definitions

Export Format:

{
  "version": "0.7.0",
  "exportedAt": "2026-01-31T...",
  "data": {
    "searches": [...],
    "analytics": {...}
  }
}

1. Virtual Scrolling: Implemented in SearchResults for large result sets
2. Debounced Search: 300ms debounce on query input
3. Lazy Loading: Results load on scroll
4. Memoization: React.memo on result cards
5. Code Splitting: Lazy load advanced components
