Is there a simple way to count occurences of one t

问题:

Is there a simple way, using PowerQuery, to count the occurences of a text string within another text string?

For instance, if I have the string, "The quick brown fox jumps over the lazy dog and the lazy dog doesn't notice," how would I easily determine that the words lazy and dog occur twice?

I know I can use Text.Contains to determine whether lazy and dog occur within the string, but I don't know a simple way to determine how many times they occur.

You can split the text, using the search word as delimiter. The number of list items minus 1, is the number of occurrences.

let
    String = "The quick brown fox jumps over the lazy dog and the lazy dog doesn't notice,",
    Count = List.Count(Text.Split(String,"dog"))-1
in
    Count
