Q2: Why are no results being found?

If no results are being found, check these common issues:

1. Verify $basedir path: Ensure it's the correct absolute path
2. Check file patterns: Confirm @files matches your file extensions
3. Permissions: Script must be able to read the directories
4. Case sensitivity: Search may be case-sensitive by default
5. Excluded directories: Check @exclude isn't blocking your content

To enable case-insensitive search:

$case_sensitive = 0;
