Hi,
I was not able to reproduce the problem. I attached a screenshot of my results and cc'ed your email. I essentially used the CSV as input and was able to find all entries. Maybe there is another encoding problem. Is the input file UTF-8? Can you provide a sample input text file? Best, Peter Am 05.07.2019 um 09:46 schrieb B.
