Background

As I looked through a generated file, I was a bit perplexed as to why some matches were missing.

Code

I went back and looked at the code I was using to generate the file, it looked OK.

Yet, at the back of my mind, I am sorry that I did not follow up on the StackOverfow Q/A post that was surprisingly detailed as to why the API that I was using might not identify all of the matches.

Text File

Why cry over spilled milk.

I went back and looked at the generated file.
