Numbers will always come before letters. This is simply the lexical order of the characters, and how the sorting algorithms I've used have always worked. I'm a little surprised that the space isn't coming before the number, though. It appears that Unicode sorting treats spaces different than ASCII sorting. Solr uses Unicode (UTF8) characters. I found this, which seems to support this idea: http://unix.stackexchange.com/questions/252419/unexpected-sort-order-in-en-us-utf-8-locale Thanks, Shawn
