将lucene-surround QueryParser部署到Solr

Question

我正在尝试将Lucene-surround QueryParser部署到Solr (1.4.0)

我被告知这很简单，只需下载surround QueryParser jar并将其添加到solr.war中的lib目录，然后在solrconfig.xml中通过添加以下行来引用它

<queryParser name="SurroundQParser" class="org.apache.lucene.queryParser.surround.parser.QueryParser"/>

当我这样做的时候，我收到了这个错误

SEVERE: org.apache.solr.common.SolrException: Error Instantiating QParserPlugin,
 org.apache.lucene.queryParser.surround.parser.QueryParser is not a org.apache.s

我应该如何继续？

我认为你需要扩展QParserPlugin。The Solr Wiki解释了如何-基本上，您的createParser方法应该返回环绕查询解析器，而不是QParser。Mark Miller's post提出了一些替代方案。
