OS X "pluginkit --match" displays the result result prefix "+, - ,!". What does it mean?

Running the terminal pluginkit -m produces the following output (non-essential lines are skipped):

 + com.apple.ncplugin.weather(1.0) - com.apple.share.SinaWeibo.post(1.0) H. com.apple.InternalFiltersXPC(2.0) com.apple.ncplugin.FindMyFriends(1.0) ! com.mycompany.MyDemoPlugIn(1.0) 

There is a question https://stackoverflow.com/a/166952/126952/ ... with the answer about the + and - prefixes.

 + com.mycompany.finderExt(1) - If the extension is enabled - com.mycompany.finderExt(1) - If the extension is not enabled 

But what a sign of exclamation ! and the strange prefix H. mean?
What does it mean when there is no prefix?

Thanks!

! means that the search sync extension does not start from the application. This is possible if your system has multiple copies of the containing application.

You can check the extension path using the following command

 /usr/bin/pluginkit -m -v -i com.mycompany.finderExt
