Is it possible to show the case with a small code fragment? DIGY

I am using Lucene.Net 2.9.2 I have a field that contains LastName|FirstName data and is un-tokenized. This field can contain diacritic characters. I have tried the following. 1. Using the SortField(name, locale, reversed) class 2. Create a custom FieldComparatorSource (this splits on the | and tries to sort by the last name portion first and then the first name if the last name is the same) 3. Adding 2 SortField fields, one for last name and one for first name. In the end they all produce the same result which is: YÀNG|YING YATES|AISLIN YATES|ALEXANDREA YATES|BRUCE YATES|DOREEN YATES|GAYELORD YATES|LAVONE YATES|LIZZIE YATES|PRUNELLA YATES|RONALD *YÀTES|RONA* YATES|TANZI YATES|TATUM YATES|TRISTAN YATES|WELDON YÀTES|XAVIOR But if I run the code from the custom FieldComparator using a List<String> Sort with a simple IComparer I get YÀNG|YING YATES|AISLIN YATES|ALEXANDREA YATES|BRUCE YATES|DOREEN YATES|GAYELORD YATES|LAVONE YATES|LIZZIE YATES|PRUNELLA YATES|RONALD YATES|TANZI YATES|TATUM YATES|TRISTAN YATES|WELDON *YÀTES|RONA* YÀTES|XAVIOR This is the correct alphabetical order Is it possible to get Lucene to sort the results the same way as the IComparer? How should I store the data in the index if I want to sort LastName / FirstName? Thanks for any help.
