解决nutch搜不到结果

• 搜索中文出现乱码：修改/etc/tomcat5/server.xml。增加URIEncoding/useBodyEncodingForURI两项。
  <Connector port="8080" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443"URIEncoding="UTF-8"useBodyEncodingForURI="true"/> 
• 网页快照中文乱码。修改页面tomcat6/webapps/nutch/cached.jsp，将content = newString(bean.getContent(details))修改为content = newString(bean.getContent(details),"utf-8")。

• 搜索不到内容。修改/var/lib/tomcat5/webapps/ROOT/WEB-INF/classes/nutch-site.xml为如下内容：
  <?xml version="1.0"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?><!-- Put site-specific property overrides in this file. --><configuration> <property> <name>searcher.dir</name> <value>/tmp/apache-nutch-1.2/crawl-20110507144354</value> </property></configuration> 
其中crawl-20110507144354是索引文件目录index的上一级目录。
