我正在尝试将Lucene-surround QueryParser部署到Solr(1.4.0)
我被告知这很简单,只需下载环绕的QueryParser jar并将其添加到solr.war中的lib目录,然后通过添加行在solrconfig.xml中引用它
<queryParser name="SurroundQParser" class="org.apache.lucene.queryParser.surround.parser.QueryParser"/>
当我这样做时,我收到此错误
SEVERE: org.apache.solr.common.SolrException: Error Instantiating QParserPlugin,
org.apache.lucene.queryParser.surround.parser.QueryParser is not a org.apache.s

我该怎么办?
答案 0 :(得分:2)
我认为你需要扩展QParserPlugin。
The Solr Wiki解释了 - 基本上你的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。
