How can I use more columns for Textprocessing?

[Paraguas]

Hi, 

is it possible to use more than one column out of textual data which is stored in csv format for the further steps in text Processing? So that e.g. one row has various colums with words that all shall be used for the final tag cloud. 

With the "String to document" node I can only choose the sources for Title, Text and the Author. Is there any possibility to use more sources for the text? 

Thank's a lot for the help

Yes, with the Unpivoting node you can generate out of all your coloumns wiith text, just one. Than you can apply the standard Textprocessing.
