st: counting the number of times a string appears in a string variable? |

Greetings, I looked through the list of string functions but couldn't find one that fits the bill. Suppose I have a string variable X, and I would like to generate a new numeric variable Y containing the number of times a certain string appeared in X. For instance X = "johnabc johncd" If I'd like to find the number of times "john" shows up in X, I hope to obtain Y = 2 Is there a function in Stata to do this? Thank you very much for your help!
