lucene:no segments* file found in org.apache.lucene.store.FSDirectory@异常

lucene创建索引中的构造函数IndexWriter(Stringpath, Analyzer a, boolean create, IndexWriter.MaxFieldLength mfl),这里的boolean create参数的意思并非是否创建索引,而是覆盖还是追加的意思。原文见官方文档:create - trueto create the index or overwrite the existing one; false to appendto the existing index

create - true to create the index or overwrite the existing one;false to append to the existing index
true:创建新的索引或者覆盖现有索引
false:追加索引到现有索引。

所以。当该参数为false,而所以目录下由不存在索引的时候,便会产生该异常。

java.io.FileNotFoundException: no segments* file found inorg.apache.lucene.store.FSDirectory@D:/lucenedir/index:files:
