How to find '-s' inside a vim search

I use Vim to read man pages. But I'm having trouble searching for variables. For example I use:

/\<-s\>

to search for '-s', but it doesn't find anything. Grrr. I see it in the file. What am I doing wrong?

From stackoverflow

• /-s works just fine for me.

  Leonard : The problem is I want it word-delimited. There are lots of -s strings there.

  Aaron Maenpaa : ":set hi" and "nnnnnnnnn..." are your friends. I mean seriously, how many "-s"s are you going to see? A hundred?

  Aaron Maenpaa : Though on second thought... It is nice to know *why* the regexp you posted didn't work. Thanks Brian.

• \< matches the beginning of a word, and - normally isn't considered a word character. Do :set iskeyword? to see what characters are considered word characters.

  Try this:

  :set iskeyword+=-
  /\<-s\>
  

  Should work then. See :h /\< and :h 'iskeyword'.

  Leonard : Perfect. Thanks.
