Subject [jira] Commented: (SOLR-1172) Hyphenation in Query Boost Function
Date Fri, 04 Sep 2009 00:05:57 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12751230#action_12751230
] 

Hoss Man commented on SOLR-1172:
--------------------------------

I haven't looked into this in depth, but skimming QueryParsing.java i *think* this is because
getId is using Character.isJavaIdentifierStart and Character.isJavaIdentifierPart ... we should
probably just be looking for anything that is not ")" or "," (since those are the only function
query special characters)

FYI: in the original bug report, the exception is missleading ... the problem there is that
a quoted string was passed where an (unquoted) field name was expected ... however if the
unquoted field name was used, then an exception like the one Trey posted would have occured.
