由于lucene最初是一个Apache Java项目，因此在此寻找特殊信息始终是一个好主意:http://lucene.apache.org/java/2_4_0/fileformats.html [

Since lucene is originally an Apache java project it''s always a good idea to also look there for specialized information: http://lucene.apache.org/java/2_4_0/fileformats.html[^] This page describes pretty well what files there are and some of the content.

Hope this helps you!
