How to filter a list of words by using filter token by content operator I have a list of 300 words but the operator can take only one word, I have read all of the solution related to this problem but no one is working for me.

thank you in advance

    With that volume of words I would suggest the Custom Stopword dictionary option I mentioned.  Just create a simple text file with all the words you don't want (each word on a separate row) and connect that as your external dictionary file.  Only the words that are not on that list will be retained.

    You can use "Replace Tokens" first to change every token you want to eliminate (this operator takes multiple rows of inputs) into something like "replaceme" and then just use a single "Filter Tokens by Content" on "replaceme" after those substitutions.

    Or you can use the "Filter Stopwords (Dictionary)" operator and use an external file of words to eliminate.
