[jira] [Commented] (SOLR-11501) Depending on the parser, QParser
should not parse local-params
[ https://issues.apache.org/jira/browse/SOLR-11501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16830248#comment-16830248 ]
Fredrik Rodland commented on SOLR-11501:
----------------------------------------
Has this broken pther use of \{!<tag|parent>} for the q-parameter? Or am I missing something. I also asked more or less the same question on the mailling list btw: [http://lucene.472066.n3.nabble.com/Unable-to-tag-queries-q-in-SOLR-gt-7-2-td4433617.html]

> Solr should not parse local-params (and thus be able to switch the query parser) in certain circumstances. _Perhaps_ it is when the QParser.getParser is passed "lucene" for the {{defaultParser}}? This particular approach is just a straw-man; I suspect certain valid embedded queries could no longer work if this is done incorrectly. Whatever the solution, I don't think we should assume 'q' is special, as it's valid and useful to build up queries containing user input in other ways, e.g. {{q= +field:value +\{!dismax v=$qq\}&qq=user input}} and we want to protect the user input there similarly from unwelcome query parsing switching.
