+### Full-Text Search on the Files Page
+

+
+### Dedicated Search Page
+
+For a more focused search experience, use the **Search** page accessible from the main navigation:
+
+1. Navigate to the **Search** page
+2. Type your query into the search box — results appear automatically as you type (or press Enter)
+3. Results are displayed in a Google-style format showing:
+   - **Document title** (linked to the file detail page)
+   - **Filename**
+   - **Document type**, **sender**, and **tag** badges
+   - **Content preview** with highlighted matching terms
+4. Use pagination to browse through large result sets
