Problem: Textmining with specific set of words

Hello everyone :smileywink:

 

I currently face a problem with searching for specific keywords within texts that are stored in a Example Set / Dataset. 

What I did so far:

 

Main Process 1: Selected the attribute "text" from the table --> Data to Documents --> Process Documents ( with a Wordlist as input)

Process 2: (getting the wordlist): Retrieve Example Set --> Selecting the Attribute for the keywords with a filter --> process Documents from Data --> connecting the "wor" output to the "wor" input from "Process Documents"

 

Problem: The results for occurences of the keywords are always the same, even if I change the text files to complete new ones ( I have multiple Example Sets containing multiple text files). The total occurences and Document Occurences are also always the same.

 

Here is the XML code:
