Those aren't really options. The syntax of the find command is

  find <options> <paths> <expression>

Those thing you list are part of the <expression> part of the command. The <options> part in BSD find, and I believe GNU find, only uses options of the form -X where X is a single character.

It's a little confusing because the man pages for both BSD and GNU find do call some of the things that appear in the <expression> part of the command "options".

Find is specifically called out in the article.

> There were a few programs that ran on Unix systems and used long option names starting with either - or no prefix at all, such as find, but those syntaxes were not compatible with Unix getopt() and were parsed by ad-hoc code.
