Hi,

First I read a txt-file and afterwards i would like to do some simple text processing steps and then i would like to export the newly stemmed and processed data to a txt data.

I got all the steps working but i just cant export results - I dont now if its clear but i would like to have a txt-file which contains the processed file as it is show in the Resulttable.

    Indeed this is not very intuitive. Of course you need the "Write Document" operator, but unfortunately this operator does not write the processed tokens. To do this you have to add the "Combine Documents" operator which does not only concatenate multiple documents, but also creates a new document with the tokens instead the original text. Thus adding this operator before the write operator yields your desired output.
