Hello, These are special characters, if you don't need them, you must escape them.
See top of the article: https://lucene.apache.org/solr/guide/8_5/the-extended-dismax-query-parser.html Markus -----Original message----- > From:Webster Homer <webster.ho...@milliporesigma.com> > Sent: Friday 12th June 2020 22:09 > To: solr-user@lucene.apache.org > Subject: eDismax query syntax question > > Recently we found strange behavior in a query. We use eDismax as the query > parser. > > This is the query term: > 1,3-DIMETHYL-5-(3-PHENYL-ALLYLIDENE)-PYRIMIDINE-2,4,6-TRIONE > > It should hit one document in our index. It does not.
