Extract the sentences containing particular words

Hi all,

I want to extract sentences which contain specific words from a table. For this I built a workflow as shown in the screenshot. But the strings to document shows error : Duplicate column name.
Is there any solution for this.

Also suggest any other workflows for extracting the sentences containing user defined words

 

Hey,

the screenshot is not very helpful. Are you sure that your input table (Table Reader node) does not have a column named "Document"?

Best,
Marc
