Some examples of illegal user queries are: "chocolate +- * chip", "chocolate - - chip", and "chocolate chip -". */ public static CharSequence stripIllegalOperators(CharSequence s) { String temp = CONSECUTIVE_OP_PATTERN.matcher( s ).replaceAll( " " ); return DANGLING_OP_PATTERN.matcher( temp ).replaceAll( "" ); } {code} This seems only to be called from: org/apache/solr/search/DisMaxQParser.java:156: userQuery = SolrPluginUtils.stripIllegalOperators(userQuery).toString(); > Dismax parser exceptions on trailing OPERATOR > --------------------------------------------- > > Key: SOLR-874 > URL: https://issues.apache.org/jira/browse/SOLR-874 > Project: Solr > Issue Type: Bug > Components: search > Affects Versions: 1.3 > Reporter: Erik Hatcher > > 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> ... > "*" ... > > at org.apache.lucene.queryParser.QueryParser.parse(QueryParser.java:175) > at > org.apache.solr.search.DismaxQParser.parse(DisMaxQParserPlugin.java:138) > at org.apache.solr.search.QParser.getQuery(QParser.java:88) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
