  Solr是一个独立的企业级搜索应用服务器，它对外提供类似于Web-service的API接口。用户可以通过http请求，向搜索引擎服务器提交一定格式的XML文件，生成索引；也可以通过Http Get操作提出查找请求，并得到XML格式的返回结果(Solr is an independent enterprise search application server, which provides API interface similar to Web-service. Users can submit XML files in a certain format to search engine servers through HTTP requests and generate indexes. Users can also submit search requests through Http Get operations and get the returned results in XML format.)
