Fixing Solr error: Cannot parse ‘audio_length:[0 to 900]’: Encountered \”

If you try to do a Solr range query like this:

fq=audio_length:[0 to 900]

You can get an error:

Cannot parse 'audio_length:[0 to 900]': Encountered \"  

The actual answer to this error is to capitalize the “TO” – the documentation Lucidworks provides is incorrect1:

fq=audio_length:[0 TO 900]
