Solr MoreLikeThis查询匹配换行符

我有一个Solr MoreLike这个查询产生了一些确定无关的结果。当我查看该查询的调试时，我可以看到该查询在换行符上匹配。Solr MoreLikeThis查询匹配换行符

这里的查询：

MLT Q = is_lesson_id：49029 &开始= 0 &行数= 3 & FL = *，得分&重量= JSON & FQ = sm_sitename {标签=网站！}：（FCM OR BCM OR CCM）& mlt.interestingTerms =细节& mlt.match.include =假& mlt.match.offset = 0 & mlt.fl =标题，正文& mlt.mintf = 2 & mlt.mindf = 1个& MLT。 minwl = 4 & mlt.boost = true & mlt.qf = title^1000 body &缩进=上& debugQuery =上

这里的解释：

这是指示错误配置的服务器上，或者是不正确地索引的内容，还是查询需要改变？

索引HTML？您可能希望将HTML标记从过滤器管道开头的文本中除去。请参阅本页上的HtmlStripCharFilter以获取更多信息：http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.HTMLStripCharFilterFactory

我可以将其用于查询分析器上的文本字段吗？ – ebeyrent 2012-03-28 21:02:51

查询解析器不使用标记器或字符过滤器，因此您需要在将格式发送到Solr之前将其格式化。如果它们只是实体，比如' '，那么编程语言中可能有一个unescape库函数。 – 2012-03-28 21:06:21

非常感谢您的帮助！我最终在查询和索引分析器中添加了带有HTMLStripCharFilterFactory的另一个文本字段，因此我可以对原始未转义的html进行索引。我的搜索查询然后在MLT查询中使用此字段。 – ebeyrent 2012-03-28 22:57:43
