You may have seen it in an article.
The reliability of information depends on the source.

Subject: Re: Re: how to get oracle to ignore an index
i cant reproduce the data for you. its internal. I tested it repeatedly. I
was very careful about the hint.
select /*+ index(<index_name>) */
select /*+ index(<table> <index_name>) */
Tried it repeatedly. I've seen it before. Sorry, I cant show you the data,
etc... I could have swarn I read in the docs that hints are just
directives and oracle does not have to use them? I cant find it right now.
Am I wrong? I'm pretty sure I have seen that several times.
