我需要过滤与cms中访问权限相对应的solr搜索结果(基于位掩码的drupal 7自定义访问控制机制).

我在tomcat6(在Debian系统上)上使用Solr 3.6.1(/var/lib/tomcat6/solr/lib/bitwise_filter_plugin.jar中的插件),而drupal模块search_api_solr和solrconfig.xml中提供了schema.xml,则使用schema.xml模块发布队列(按照SOLR-1913问题扩展).

Solr查询…

http://solr:8080/solr/select?qf=t_title&fl=*,score&fq={!bitwise field=is_bitmask op=AND source=1234}*

…在错误日志中失败,并显示以下消息：

Sep 27, 2012 8:57:41 AM org.apache.solr.core.SolrCore execute

INFO: [] webapp=/solr path=/select params={qf=t_title&fl=*,score&fq={!bitwise+field%3Dis_bitmask+op%3DAND+source%3D1234}} status=500 QTime=15

我在错误消息中只能看到的插件是由solr调用的.

任何帮助,将不胜感激,谢谢.
