Text mining: Filter words from dictionary

Kassandra

I am trying to count the occurencies of words in documents from a given list of words (dictionary). With Filter Tokens (by content) I can only use one single word, otherwise I only get either all words or none. How can I get a vector matrix with the occurences/frequences only of the words from the dictionary?
