Question

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

    <?xml version="1.0" ?>

我有一个名为“foorightfoo”的对象。当我搜索“foo”时，没有出现，但是当我搜索“foorightfoo”的答案来了。当我从太阳能管理面板检查时，同样的情况继续... 我的搜索仅适用于完全匹配。任何想法？

Answer 1

实际上我通过操作schema.xml的最后一部分来修复了这个问题，比如

- <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更改搜索的字段类型可以实现技巧

Answer 2

您需要在最后附加一张外卡*，因此请查询

q=title:foo*

Solr使用Django只找到完全匹配
