Drupal 8.x

I would like to build a search view with these feature:
In the pages display only one field that searches in taxonomy terms and in some text fields.
In the result page show the other secondary options (city, region, etc) to refine the result.
I know that as backend I will have to use Apache Solr, but in the meantime I would like to try to build the view to see if I am following the right way.

Is it possible to do it with views, and if so where can I find some examples? I've found something, but nothing that looks like it...

I have created a module that generates a license in the user field and I want to run its function when the user has completed the order (Paid).

I would be glad for any example or link, I just started creating modules)

If there is no "purchase completed" event, how can I view all commerce events?

Question on drupal.stackexchange.com

Does anyone have a solution for the rules_ban errors when the update.php script is called? I understand that the module has been deprecated but it seems that something was missed causing the errors.

Thanks in advance

Hello, I have a view that lists nodes of a given content type. When I add the fields 'Comment Statistics: Comment count (Number of Comments),' 'Comment Statistics: Last comment time (Most recent comment),' and 'Comment Statistics: Last comment author,' it displays data from all the comments on the site in each listing. What I want is for the comment count, last comment time and comment author to refer only to those comment items associated with each node in the list.

The instructions at https://www.drupal.org/docs/official_docs/en/_local_development_guide.html say to execute the following commands to create a new Drupal application (after ddev has been installed):

# Replace my-site-name!
export SITE_NAME=my-site-name
composer create-project drupal/recommended-project $SITE_NAME
cd $SITE_NAME

And it says that this "will create a new directory and populate it with Drupal (and is dependencies)."

I see lots of examples of how to create a single menu item from the .links.menu.yml file and can do that but am trying to figure out how to extend that to building a complete main navigation menu with x level1 menu items and each of those then has varying numbers of sub-menus.

I'll scour github but if anyone has a tutorial they have used please let me know.

Thanks
