Problem: If I use the following code;

dataset[Select[#"Column 1" != "" &]]

I get all rows that do not have an empty string, and if I use the code;

dataset[Select[#"Column 1" != "Help" &]]

I get all rows that do not include the string "Help".

Question: How do I get all rows that do not contain the keyword help? I can't understand why there isn't, or seem to find, a simple way to indicate that "Help" is not the entirety of the string, which is frustrating me.

Your help would be much appreciated.

Sincerely, Lewis
