Использование SendScintilla в pyqt5 QScintilla

Question

Я ищу строку в окне qscintilla

import sys
from PyQt5 import  Qsci
from PyQt5.QtWidgets import *

app = QApplication(sys.argv)
window = Qsci.QsciScintilla()
window.show()

text = "Hello world"
window.setText(text)
scintilla = window.SendScintilla
scintilla(window.SCI_TARGETWHOLEDOCUMENT)
pos = scintilla(window.SCI_SEARCHINTARGET,len("world"),"world")
print(pos)
app.exec_() 

я пытаюсь найти "мир" в текстовой строке, используя Sendscintilla, когда я запускаю этот код, он показывает эту ошибку

    pos = scintilla(window.SCI_SEARCHINTARGET,len("world"),"world")
