GetFileListAsync - searchPattern

[tho666]

I've started using this and my need is to be able to do some custom searches for files. I have a couple of questions in regards to this:

1. Can I use some custom search pattern to be able to do TopLevel/All directory tree kind of search?
2. Is searchPattern a Regex type of pattern? (Any details would be appreciated as I can't find any info on this.)

Thanks!
