Mikhail Khludnev commented on SOLR-14557:
-----------------------------------------
Ok. There are two places where local params are parsed:
# QParser.parseLocalParams() when string starts with curly brace {
# JavaCC QueryParser.jj SOLR-4093
SOLR-11501 banned edismax from the former option. But the former option is
unable to handle {{\{!parser}(foo)}} that might seem like a bug, but after
thinking a little I've though it's reasonable. Think about {{(\{!term}foo)}},
it should be parsed to {{foo}} undoubtedly, but {{\{!term}(foo)}} behavior
quite depended on subordinate parser, TermQParser should receive parenthesis,
but LuceneQParser probably shouldn't.
So, I resolved it just by advising customer for tweaking syntax:
Before 7.2 {{\{!join ...}(... )}} -> after 7.2 {{\_query_:"\{!join ...
defType=edixmax}....."}}
Sorry for the noise.
