How to use moviesearch plugin?

Hi,

I've downloaded moviesearch plugin but I haven't found how to use it. We can access it in the menu of MoviePlayer. I thought I can use it to search a movie which the title contains a word we can type but when I launch it, I've the error message :

"Improperly launch plugin

 Aborted"

Somebody can explain what we can do with this plugin and how to use it?

Thank you .
