--- Comment #1 from David Cook <dcook at prosentient.com.au> ---
QueryParser takes this as input:

(authtype:UNIF_TITLE) match-heading:"McGraw-Hill \\"Demystified\\" series"
#AuthidAsc

And it outputs this:
 @or @attr 1=Local-Number @attr 7=1 0 @and @and @attr 1=authtype @attr 5=100
@attr 4=6 "UNIF_TITLE" @and @attr 1=Match-heading @attr 4=1 @attr 5=100 @attr
6=3 "Demystified\\\\"" @attr 1=Match-heading @attr 4=1 @attr 5=100 @attr 6=3
"series\\"" @attr 1=Match-heading @attr 4=1 @attr 5=100 @attr 6=3 "McGraw-Hill
\\"

Which causes ZOOM::Query::PQF to throw a fatal error:
ZOOM error 20003 "can't set prefix query" (addinfo: "@or @attr 1=Local-Number
@attr 7=1 0 @and @and @attr 1=authtype @attr 5=100 @attr 4=6 "UNIF_TITLE" @and
@attr 1=Match-heading @attr 4=1 @attr 5=100 @attr 6=3 "Demystified\\\\"" @attr
1=Match-heading @attr 4=1 @attr 5=100 @attr 6=3 "series\\"" @attr
1=Match-heading @attr 4=1 @attr 5=100 @attr 6=3 "McGraw-Hill \\"")
