Why is there no O_SEARCH flag for an open function in Open Open?

Question

Let's say I need to get a file descriptor for a file (or directory) that has only permission to execute (or search).

The X / Open norm defines the O_SEARCH flag for the open () function. See http://pubs.opengroup.org/onlinepubs/9699919799/functions/open.html

However, Linux does not work. There are only 3 flags available (O_RDONLY, O_WRONLY and O_RDWR). See http://man7.org/linux/man-pages/man2/open.2.html

Why? And how can I get a fd directory with a single permission to search?

thank
