My Q2 is:
I prefer not to add also an Excerpt to every each Book, cutting manually the Body content.
AFAIK only Excerpts can be cut by words, but that would be great to be able to cut any multiline text that way.
So could you have also a workaround?
Hello. Thank you for contacting the Toolset support.
Do you mean you have other multiline fields added to your posts and you want to have control on multiline field content and restrict with words or characters?
If you do not have post excerpt field added to your post and you will set to display post excerpt field, the settings you set to display with post excerpt field will be applied on post content (body) field.
You can add a "Single Field" block to your view to display the post excerpt and restrict it with the character or word count. Please check the following screenshot: hidden link
