How to interact with my document editor and invoke the editor's global search function.

[THL1234]

I want to interact with my document editor and invoke the editor's global search function. How can I use the callCommon or executeMethod method to achieve this requirement？
the code doesn't work

this.connector.callCommand(function() {
  var oDocument = Api.GetDocument();
  var aSearch = oDocument.Search("xxx"); // xxx is someting to search
  aSearch[0].SetBold(true);
}, function() { console.log("callback command"); });

We've added Search and SearchAndReplace methods. Thanks
