The Google Scholar page has been updated that there is no 'RecaptchaOptions' in the page when Google is checking if you are a robot. Besides, the default order of open an URL in order to disable the robot checking would open system browser firstly, which would not resolve the robot checking. Instead, using zotero internal browser is helpful, so I prioritized the internal browser.
For discriminating situations when there is no search result or the result has no citing number like in #26 , I make the extra field 'No Citation Data' when the search result is empty by counting result div elements with class 'gs_r gs_or gs_scl'.
