When I search for words that appear in my H5P activities, they don't appear in the results. Is there a way to make Moodle search inside H5P activities?
Thanks a lot
Looking at that plugin, it doesn't appear to implement the Moodle global search API. You'll need to ask the plugin developers to add support.
Thanks Mark, I was suspecting something of the sort... bad news 
Just replying so I can follow this new forum.
is there a way to know or be notified if there is any developer working in implementing H5P in the global search?
Yes, information on the work being done on H5P can be found in this post and the references there to the tracker items with details: https://moodle.org/mod/forum/discuss.php?d=390359#p1573842
