Hey, Use a StringField instead of a TextField for the title and your test will pass. Tokenization which is enabled for TextFields, is breaking your fancy title into tokens split by spaces, which is causing your docs to not match. https://lucene.apache.org/core/9_11_0/core/org/apache/lucene/document/StringField.html
