Solr使用Django只能找到精确匹配

我在索引页上有一个django应用程序和一个搜索栏。我安装了haystack和solr。 我键入python manage.py build\u solr\u schema，并将以下xml粘贴到example/solr/conf/schema.xml

我有一个名为“FoorRightFoo”的对象。当我搜索“foo”时，没有显示任何内容，但是 当我搜索“FoorRightFoo”时，答案就来了。当我从solar管理面板检查时，同样的情况还在继续。。。

我的搜索只针对精确匹配。有什么想法吗

您需要在末尾附加通配符

*

，因此

q=title:foo*

实际上，我通过像这样操作schema.xml的最后一部分解决了这个问题

- <field name="text" type="text_en" indexed="true" stored="true" multiValued="false" />

+ <field name="text" type="ngram" indexed="true" stored="true" multiValued="false" />

+

使用ngram更改搜索字段类型的方法仍然相同。。还可以，但是空了。分析工具应该可以帮你自己调试。查看在索引时为

foorRightFoo

生成的令牌。对于默认的Solr 4.0示例安装，它位于。为您的路径绘制地图并尝试
