Добрый день. Пытаюсь освоить работу с Lucene.NET с NHibernate.NET.

Ну и небольшой скрипт для вставки данных в базу...

INSERT INTO TempBook (TempBookID, Author, Name, Summary) VALUES ( 1, 'Eric Evans', 'Domain-Driven Design: Tackling Complexity in the Heart of Software', 'This book provides a broad framework for making design decisions and a technical vocabulary for discussing domain design. It is a synthesis of widely accepted best practices along with the authors own insights and experiences')
INSERT INTO TempBook (TempBookID, Author, Name, Summary) VALUES ( 2, 'John Doe', 'Foo book NHibernate', 'Foo series book')

И какие танцы с бубном не делай всегда возвращается нуль записей!!!
Есть какие нибудь идеи? |
