Error in line with SearchAndReplace function

DocumentBuilder version: 4.4.1
Installation method: docbuilder.exe
OS: Windows 7 x64
I just copied this code from official api documentation (ONLYOFFICE Api Documentation - SearchAndReplace), put it in a .docbuilder script-file and… it doesn’t work.

builder.CreateFile(“docx”);
var oDocument = Api.GetDocument();
var oParagraph = oDocument.GetElement(0);
oParagraph.AddText(“This is the first sample text. The serial number of this sample text was replaced here.”);
oDocument.SearchAndReplace({“searchString”: “first”, “replaceString”: “second”});
builder.SaveFile(“docx”,“c:\test.docx”);
builder.CloseFile();

Error is Uncaught TypeError: oDocument.SearchAndReplace is not a function (WHAT?)
What is that? And, of course, script doesn’t return any file.

Hello,
This is some really obsolete version of the document builder. Where have you downloaded it from?
Please install the current one (7.1.1) and use it.

7.1.1 works. Thanks.
