Well there is no API available from Google for Google Scholar. That means that the only approach to get data out of it is by web-scraping. That can be a very tedious and time-consuming and possibly a very unreliable process. But there are already Python scripts available to do exactly this. One could also use something like PhantomJS or pjscrape or something similar to fetch data to be relieved of the huge effort to write it yourself.
Then you would run some scripts before you run your load script and then read the retrieved file(s) from your load script. Basically not using a connector approach.
