I ran into an interesting problem this evening. It actually started a few days ago when I noticed that my qq script wasn’t returning searches within the @(metadata) I set up in the note bodies. I figured I’d come back to it when I had time. Then I got a couple of emails from readers who had also noticed this, so I started digging. It turned out that Spotlight had stopped indexing text content of all files with the .md extension. If I renamed the file to .txt or .mmd, it would work fine, but something had convinced Spotlight that Markdown files were source code, not text. My source code importers don’t handle Markdown, so I was getting no content imported.
