In order to search for a special character in Solr, you need to use the right escape syntax. Special characters in Solr query strings include characters like + - && || ! ( ) { } [ ] ^ " ~ * ? : \ , and spaces. To search for a special character, you need to escape it with a backslash (). For example, if you want to search for the character "+", you would need to escape it like this: "+". This tells Solr to treat the character as a literal character to be searched for, rather than as a special operator. By properly escaping special characters, you can conduct more precise searches in Solr.
