How can I add body class based on path / page specific class - Drupal 9?

It's a simple 3 line code to achieve adding the body class based on the URL. Sometimes, we need to overwrite the existing styles based on the page. so, we need the page specific class.

Go to your THEME_NAME.theme file & add this below HOOK.

 * Implements hook_preprocess_html().
function THEME_NAME_preprocess_html(&$variables) {
  // Get the current path
  $current_path = \Drupal::service('path.current')->getPath();
  $internal_path = \Drupal::service('path_alias.manager')->getAliasByPath($current_path);

  // Assign it to body class 
  $variables['attributes']['class'][] = str_replace("/", "", $internal_path);

Make it simple :)

How to index data in the database for search?

- Indexing is an important feature of MySQL. It supports different type of indexes like primary key index, unique index, normal index and full-text index. Indexes help to speed up the retrieval of data from MySQL database server.

- Drupal's search engine indexes the text content of the nodes on your site

- The search engine indexes at intervals you choose by setting "cron runs."  Cron is not a part of Drupal. It's a scheduler that resides on your server and runs tasks at intervals, which you specify. 

how does search works in drupal?

Site-wide Boolean keyword search of Nodes and User names

- Indexing isn't instant in the drupal search
- Your new content will not be indexed instantly after it has been added to the site.
- Go to Configuration > Search settings click the "Re-index site" button.
- The correct way to get your site's content indexed is to go to Configuration > Cron. Drupal's Search module requires a cron job to run correctly.
