+The search works by generating a JSON search index which Alpine.js loads asynchronously. There are two ways to access the search:
 
-Two ways to access the search are added, one is a full page search screen that will be saved to `docs/search.html`.
-
-The second method is a button added to the documentation pages, similar to how Algolia DocSearch works. Opening it will open a modal with an integrated search screen. You can also open the dialog using the keyboard shortcut `/`.

 >info The full page can be disabled by setting `create_search_page` to `false` in the `docs` config.
 
+### Search Features
+
+The search implementation includes:
+- Real-time search results as you type
+- Context highlighting of search terms
+- Match counting and search timing statistics
+- Dark mode support
+- Loading state indicators
+- Keyboard navigation support
+- Mobile-responsive design

 ### Hiding Pages from Indexing
 
-If you have a large page on your documentation site, like a changelog, you may want to hide it from the search index. You can do this by adding the page identifier to the `exclude_from_search` array in the `docs` config, similar to how navigation menu items are hidden. The page will still be accessible as normal but will not be added to the search index JSON file.

 ### Live Search with the Realtime Compiler
 
-The Realtime Compiler that powers the `php hyde serve` command will automatically generate a fresh search index each time the browser requests it.
+When using `php hyde serve`, the Realtime Compiler automatically generates a fresh search index each time it's requested, ensuring your search results stay current during development.
