将lucene与h2数据库一起使用时出错

我想在我的项目中实现一个使用h2数据库(嵌入式)的小型全文搜索。据我所知,我必须使用lucene作为全文引擎来查找相关结果(而不仅仅是包含结果)。但我不能用它。这个区块是lucene启动:

FullTextLucene.init(connection);
FullTextLucene.createIndex(connection, "PUBLIC", Tables.COURSES_DETAIL, Columns.NAME);

我也是这样用的:

stmt.execute(
      "create alias if not exists FTL_INIT for \"org.h2.fulltext.FullTextLucene.init\"");
  stmt.execute("call FTL_INIT()");
  stmt.execute(
      String.format("CALL FTL_CREATE_INDEX('PUBLIC','%s',%s)", Tables.COURSES_DETAIL, "NULL"));

但这个错误发生在运行时:

Error creating or initializing trigger "FTL_COURSES_DETAIL" object, class "org.h2.fulltext.FullTextLucene$FullTextTrigger", cause: "org.h2.message.DbException: Class ""org.h2.fulltext.FullTextLucene$FullTextTrigger"" not found [90086-197]"; see root cause for details; SQL statement:
CREATE TRIGGER IF NOT EXISTS "PUBLIC"."FTL_COURSES_DETAIL" AFTER INSERT, UPDATE, DELETE, ROLLBACK ON "PUBLIC"."COURSES_DETAIL" FOR EACH ROW CALL "org.h2.fulltext.FullTextLucene$FullTextTrigger"

我将h2库降级到最新的“稳定”版本(1.4.196)后,错误已更改:

Caused by: java.lang.NoSuchMethodError: org.apache.lucene.store.FSDirectory.open(Ljava/io/File;)Lorg/apache/lucene/store/FSDirectory;

有时这个错误:

Exception calling user-defined function: "init(conn1: url=jdbc:default:connection user=INFC): org.apache.lucene.store.FSDirectory.open(Ljava/io/File;)Lorg/apache/lucene/store/FSDirectory;"; SQL statement:
call FTL_INIT()

我找到了解决办法。但我知道这不是最好的。
我将lucene lib降到了3.6.2,并使用普通查询而不是 FullTextLucene 功能。
