Hoss Man commented on SOLR-4538:
--------------------------------
This is so weird. Somehow the query parser is deciding to ignore the last N
chars of the string, where N can vary depending on the string. in the examples
posted to this issue so far, it just so happens that N winds up being the exact
length of the last clause in the math, but in other cases you'll get an invalid
date math expression which causes an error..
