The null fields were returned because of this analyzer used to index and search : ` private readonly StandardAnalyzer _standardAnalyzer = new(AppLuceneVersion);` Meaning some lastname (Will, To, etc.) were considered stopWords. fields are therefore set to NULL and the sort would sort them like the field was empty (null). Modifying to `private readonly StandardAnalyzer _standardAnalyzer = new(AppLuceneVersion, CharArraySet.EMPTY_SET);` solved the issue. IMHO, stops words set should be opt-in, and constructor that does not have the CharArraySet's parmater should default to CharArraySet.EMPTY_SET not the ENGLISH_STOP_WORDS_SET. Mostly because : Not everyone is building search engines for english only. Not everyone is build search engines for common words only. Using default ENGLISH_STOP_WORDS_SET is assuming a certain business case / usage of the search engine... But really it should not interfer with the context of usage. -- This is an automated message from the Apache Git Service.
