Counting the number of times a partial value appears in a column

Right now, I'm trying to find a way to count the number of times a certain phrase appears in a column.

I'm currently using this formula for exact values: COUNTIF(A1:A5,"Hello"), but this only works if an entry in a column is exactly: "Hello"

I want to be able to count a column even if it has more words, such as "Hello how are you" etc., and this column would be counted because it has the word "hello" in it.

Any tips?

It worked! Thank you!
