Hi,

Thank you for contacting us.
 
I tested the attached code snippet but it seems that it is working as expected on my end. My guess is that the problem could be related to incorrectly structured document. For this reason, I would ask you to send us exact steps to reproduce, document file and the searched text. Once we are able to reproduce the issue, we will do our best to assist you. 

Regards,
