Hi thank you for your answer, although that was not what I hoped to hear.
In my question I was referring to "articles". If I understand your answer correctly, you say that "articles" are less complex than pages. But nevertheless, they are not previewable with Smart Search so far. There is one SP Page Builder Search Plugin that I thought would be the interface between Joomla Smart Search and Page Builder articles and pages, which doesn't seem to be the case at the moment. If I understand you correctly, this functionality might be offered somehow in the future, correct?
in general we don't support Flex template
I know, but I also have several SP Page builder licenses besides Flex (and qualify as customer), and in this case, only you as developer of SP Page Builder can create that functionality. So I'm glad you added my request. I'm sure I won't be the only one wanting preview texts for SP Page Builder in the hit list of Smart Search.
Best regards,
Georg
