Hello, I am running Solr 8.11.1 and running into an issue with stream api. Looks like searches break when the data contains the backtick character( ` ). Eg: http://host-name:8983/solr/MyCollection/stream?expr=search(MyCollection,q="My_Field:Foto`s",fl="field1",qt="/export") <http://pidx.idcprodcert.loc:20000/solr/sharepointindex_036DE237-A69B-4E7E-929E-62C2AB7A7323_multinode/stream?expr=search(sharepointindex_036DE237-A69B-4E7E-929E-62C2AB7A7323_multinode,q=%22slevel_Url_8:Fotos%22,fl=%22contentid%22)>
Upon further investigation, found that the below change was introduced in Solr 8.5 to replace ` with " in StreamExpressionParser which is the root cause. https://github.com/apache/solr/blob/main/solr/solrj-streaming/src/java/org/apache/solr/client/solrj/io/stream/expr/StreamExpressionParser.java#L138 Associated JIRA: https://issues.apache.org/jira/browse/SOLR-14139 Is there a workaround to get the streaming query working? This is across multiple shards so I can't use /export directly. If there is no workaround, in my humble opinion, this seems like a breaking change and should be considered for rolling back, or the implementation should be rethought. Thanks, Rahul
