This variable is semi-obsolete and probably should always be true.  It
is better to limit inheritance to certain tags using the variables
`org-use-tag-inheritance' and `org-tags-exclude-from-inheritance'."

"org-tags-match-list-sublevels  +  search +LEVEL>n " is a very useful tip, if you have many sublevels with many different tags,
it can not lost search results nearly, why we will semi-obsolete it?

I do not understand your remark. Could you clarify what you mean? Do you
have any use case for a nil `org-tags-match-list-sublevels' that cannot
be handled with tag inheritance?

Thank you.

I seach "story" info with: "story+LEVEL>1", if I want to know more details, I search "story+LEVEL>2 ... 3 ... 4"  with  a user-define one key command help.
