Hi. I have a string variable that comprises of multiple words with no fixed order/that is not the same combination of words across rows/observations . I want to generate a new variable that is equal (extracts) certain words from the string variable. For example, my string variable may contain "Cancer, breast; worldwide, neuronal, launched". I want to generate a variable stage that extracts only "launched" for this particular row/observation. There are just five words that I want to extract from the string variable across the entire dataset and no single row/observation carries more than one of the words that I want to extract. Any guidance on how to do this will be much appreciated.

Thanks.
