java - 使用 Solr 和 Spring 自动完成 - 多个单词的问题

Question

我已经使用 Spring Data Solr 为位置数据库建立了索引。我有以下字段:

   <field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" /> 
   <field name="name" type="text_ws" indexed="true" stored="true"/>
   <field name="autocomplete" type="lowercase" indexed="true" stored="false"/>

我正在尝试实现自动完成功能。我的 ajax 调用由 Controller 处理，该 Controller 通过以下方式调用存储库:

List<POISearch> findByAutocompleteStartingWith(String autocomplete, Pageable pageable);

这对于“加利福尼亚”或“洛斯”等搜索效果很好。但是当我尝试使用“Los Ang”等多个单词时，我遇到了异常:

有什么解决办法吗？

Answer 1

使用最新版本的 spring-data-solr，您可以执行以下操作:

List<POISearch> results = repository.findByAutocompleteStartingWith(Arrays.asList("los", "ange"));

效果很好!
