在 solr 4.9 中使用 q=*:* && q={keyword} && q=field:{keyword} 查询

Query with q=*:* && q={keyword} && q=field:{keyword} in solr 4.9

想问一下为什么q=love没有return结果?希望大家帮帮我。非常感谢。

这是我的 schema.xml 文件:

这是我的 solrconfig.xml 文件:

这是 data-config.xml 文件:

<dataConfig>
<dataSource type="JdbcDataSource"  driver="com.mysql.jdbc.Driver" url="jdbc:mysql://127.0.0.1/sieunhac_development"  user="root"  password=""/>
<document name="musics">
<entity name="musics" pk="id"
  query="select p.id, LCASE(p.title) as title, birthday_singer, p.type_music from musics p order by updated_at desc;">
  <field column="id" name="id" template="id"/>
  <field column="title" name="title"/>

  <field name="type_music" column="type_music" />
</entity>
</document>
</dataConfig>

如果您查看 solrconfig.xml 文件,您会看到 /select requestHandler 配置了默认搜索字段如:

<lst name="defaults">
  <str name="df">name</str>
</lst>

在这里,您可以输入您想要的字段,例如:

<lst name="defaults">
  <str name="df">title</str>
</lst>

您可以查看另一个关于 this subject and the Solr Documentation 的主题。

更新

要回答您的评论,您可以在 schema.xml 中创建一个新字段:

<field name="searchable_field" type="text_general" indexed="true" stored="true"  multiValued="true" />

之后,您可以在新字段中复制所需的字段:

<copyField source="title" dest="searchable_field"/>
<copyField source="author" dest="searchable_field"/>
<copyField source="production" dest="searchable_field"/>

最后,您只需将这个新字段放入 solrconfig.xml:

<lst name="defaults">
  <str name="df">searchable_field</str>
</lst>
