First off Thank You. I am new to KNIME and I am trying to do a word count of a PDF article. I have the workflow started, but I am getting “Warning: String Comparison is used for range checking. May not work as expected!” I am in version 5.1.0. What am I doing wrong?

Hi @mattmc513 and welcome to KNIME Community Forum,
The “range checking” is used for numeric columns where you want to filter a range of values based on the lower bound and/or higher bound.
May I ask what do you want to filter?

My goal is to have KNIME read a PDF and count the number of times a word is used. That word would identified by a list that I define, such as COVID, Surgery, Age, etc.
So you need to count them first, right?
You can use a GroupBy node and group on terms and use the “Count” aggregation on any other column (count missing values). Then you can use the Row filter node to keep all terms with count more than 5 for example.
