So I loaded a genre folder and it contains several albums. One of the album is "18 Months". I've verified that there are no leading/trailing spaces in the album tag for this album.

I tried these filters to try:

```
ALBUM IS "18 Months" (works)
ALBUM CONTAINS "18" (doesn't work. returns nothing)

```

According to this page ([Filter and Search – Mp3tag Documentation](https://docs.mp3tag.de/filter)), my syntax for substring search should work.

I am using version 2.85.

Thanks for the help.

I cannot find any information about the keyword CONTAINS on that help page.  
Perhaps there is no such keyword?

Try HAS instead.
