Comment:

 The string that you are matching against when you search with `--variants`
 is not the name of each variant individually; it's the names of all
 variants, in the order in which they're defined in the portfile,
 concatenated with spaces. (I don't know if that was intentional, and I
 don't know if it's documented.) So for example:

 {{{
 $ port search --variant --line --regex '^java csharp glib2 php erlang rust
 nodejs swift universal$'
 thrift  0.13.0  devel   framework for scalable cross-language services
 development
 }}}

 So for example if you're looking for ports that contain a php variant, you
 can do it with the current search implementation this way:

 {{{
 $ port search --variant --line --regex '(^|\s)php\d*($|\s)'
