    You can easily use your dictionary. Just add a "Filter Stopwords (Dictionary)" operator from Text Processing/Filtering (Text mining extension) to your document processing and select the file.

    Thank you for your immidiate reply

    Are there any specifications that I have to follow for the txt document? Like comma delimited or seperators among words?

    Does UTF-8 supported?

    Thank you in advance

    The documentation of that operator contains all required information: one stop word per line, and the encoding (UTF-8 or whatever you like) can be selected with the encoding parameter.

    Best regards,

    Hi again after a long time,

    1. Yes but is there any tutorial for how I can add a custom filter stop words operator?

    2. Do I have to develop something? Is there any tutorial for that?

    3. Where can I find the documentation of filter operator? Is this helpfull as a tutorial?

    Sorry for the silly questions but I can not find the answer

    Thank you in advance
