20200603 Pikairos iterate over a list and optimize speed of the searching

What I have so far:

I have a list of strings (per row around 2000 words)
Columns with words (around 300 words per column) which ones I have to compare with list of strings
Input from the user for number of hits that has to happen

What I want to do?

I want to compare each word from the list of strings with each word from the columns with words. How can I do that?
I want to optimize my search. How? Example: if word on position 133 in list of strings has a match with 53rd word from the column of words I want KNIME to check if user entered one hit has to happen or more hits are required…if just one hit is required I want that KNIME stops iterating over the rest of the list of strings. If number of hits is 2,3,4,5 or more, KNIME should continue iterating until the count of hits is the same that user entered.
How can I do that?

Example of solution for this would be amazing. Thanks in advance.

Kind regards,
Denis
