Question

以上是我的索引结构：我想使用solr auto complete获取制造商相应的模型。假设我将applianceCatagory = Boilers，manufacture = ariston和查询字符串传递给＆＃34; cla＆＃34;然后所有与ariston制造相对应的模型都应该显示..我做了一些java编码来获取下面给出的值：但我只能获取以小写字符开头的模型，如果我传递小写查询字符串并且相同对于大写：请帮助!!谢谢你的语气。

您的/sugest SearchHandler定义了"spellcheck.dictionary"两次：一次用于title_autocomplete字段，一次用于models字段。除了我不知道solr在指定两次相同的键时表现如何，我没有在配置中的任何地方看到models_autocomplete字段，所以你的默认搜索或你的sugest组件都没有使用它字典来查询它。

编辑：

将model切换为models_autocomplete并查看是否有效。还可以考虑将默认qParser切换为edismax并指定多个搜索字段。当然，假设您的自动提取请求使用/sugest网址

如何使用solr实现嵌套索引的自动完成？
