아래 가이드를 토대로 정책 설정 화면을 만들어줘.
화면요소는 당연히 한국어여야해. 기억해줘.

Design a comprehensive search interface for an "Online Information Analysis System" that allows users to find and filter mentions across multiple online sources. The interface should include:

1. Top section with an advanced search form:
   • Large search bar with placeholder "Search keywords, phrases, or sources..."
   • Search options toggle revealing:
     • Date range picker (From/To)
     • Source type checkboxes (News, Social Media, Blogs, Forums, etc.)
     • Sentiment filter (All, Positive, Neutral, Negative)
     • Language selector
     • Boolean operator toggles (AND/OR/NOT)
   • "Search" and "Clear" buttons
   • "Save Search" button to store search parameters
2. Left sidebar with refinement filters:
   • Collapsible filter sections:
     • Date filters (Today, Yesterday, Last 7 days, Last 30 days, Custom)
     • Source categories with count badges
     • Sentiment distribution with horizontal bar indicators
     • Top domains with count badges
     • Author/publisher filters
     • Content type filters (Article, Post, Comment, etc.)
   • "Apply Filters" button at bottom
   • "Reset All" link
3. Main content area showing search results:
   • Sort options (Relevance, Date, Engagement, Influence)
   • View toggle (List/Card view)
   • Results count summary
   • Results list where each item shows:
     • Publication date and time
     • Source name with icon indicating type
     • Headline/title with matching keywords highlighted
     • Content snippet with matching keywords highlighted
     • Sentiment indicator (colored badge)
     • Engagement metrics (views, shares, comments)
     • "View Details" button
   • Pagination controls at bottom
4. Right sidebar (collapsible) with:
   • "Search Analytics" section showing:
     • Small chart of results over time
     • Top keywords found in results
     • Sentiment distribution mini-chart
   • "Related Searches" suggestions
   • "Recent Searches" history

Make sure the design is clean and focuses on readability with proper spacing between elements. Use subtle shadows and borders to separate sections. Include empty states for when no results are found. Ensure the interface is fully responsive and maintains usability on smaller screens by stacking elements appropriately.
