searching whole word in Vim (dash character)

I know for searching a whole word I should use /\<mypattern\>. But this is not true for dash (+U002d) character and /\<-\> always fails. I also try /\<\%d45\> and it fails too. anyone know the reason?

Edit2: As @bobbogo mentioned dash is not in 'iskeyword' so I add :set isk+=- and /\<-\> works!

Edit1: I think in Vim /\<word\> only is valid for alphanumeric characters and we shouldn't use it for punctuation characters (see Edit2). I should change my question and ask how we can search punctuation character as a whole world for example I want my search found the question mark in "a ? b" and patterns like "??" and "abc?" shouldn't be valid.

As OP said. In order to include dash - into search just execute:

:set isk+=-

Thats all.

Example: When you press * over letter c of color-primary it will search for entire variable name not just for color.

\< matches the zero-width boundary between a non-word character and a word character. What is a word character? It's specified by the isk option (:help isk).

Since - is not in your isk option, then - can never start a word, thus \<- will never match.

I don't know what you want, but /\>-\< will match the dash in hello-word.
