Thanks for your anwser.
Unfortunaly i tried both and it doesent work.

I installed V8 app. Odoo show me that the app should be installed, but no funktion. 

I also tried V10, like you explained but also no luck.

The app have really less code, but i dont know what do change...
Maybe someone is here who already use this app in V9.0 and could send me the file.

Code in the search.js

openerp.web_advanced_search_wildcard = function(instance){

var _lt = instance.web._lt;

instance.web.search.ExtendedSearchProposition.Char.prototype.operators.push(

{value: '=ilike', text: _lt("matches")}

);

};
