Description

Dismax is supposed to be immune to parse exceptions, but alas it's not:

http://localhost:8983/solr/select?defType=dismax&qf=name&q=ipod+AND

kaboom!

Caused by: org.apache.lucene.queryParser.ParseException: Cannot parse 'ipod AND': Encountered "<EOF>" at line 1, column 8.
Was expecting one of:
<NOT> ...
"+" ...
"-" ...
"(" ...
"*" ...
<QUOTED> ...
<TERM> ...
<PREFIXTERM> ...
<WILDTERM> ...
"[" ...
"{" ...
<NUMBER> ...
<TERM> ...
"*" ...
