最近看研究了一下搜索引擎(COMPASS)，学到的东西不多，但还是把所学的东西在这里记录一下，本人用的是COMPASS1.2
下载地址：https://compass.dev.java.net/files/documents/4669/71790/compass-1.2-with-dependencies.zip
本人用的是里面带的一个例子(petclinic)，主要的配置文件有：petclinic-servlet.xml,applicationContext-hibernate.xml,petclinic-cpm.xml,petclinic-cmd.xml,petclinic-hbm.xml,compass.cfg.xml(查找资料后，为了用paoding中文分词而加上)。
注：配置文件中的注释都是网上资料或本人对其的理解，如果有误还请指教，以免误导学习者。
