Solr dismax 查询 returns 没有数据，而标准查询有

Question

我在这样调用查询时找不到任何结果:

http://localhost:8983/solr/somecore/select?q=title:king&wt=json&defType=dismax

但是像这样调用查询：

http://localhost:8983/solr/somecore/select?q=title:king&wt=json

按预期找到 9 个文档。

我尝试了各种方法（例如 qildcard：:，无济于事）。

如果有人能指出问题或文档来解释我做错了什么。

如果重要的话，schema.xml如下：

Answer 1

得到解决方案，出于某些我不知道的原因，除非我们定义应该使用哪个字段进行过滤，否则 q=king 将无法工作，在我的例子中：

http://localhost:8983/solr/somecore/select?q=king&wt=json&defType=dismax&qf=title+body

PS

当然"title:"也应该省略。我在原始问题中没有提到它，但我在查询中尝试了有无它。

Solr dismax 查询 returns 没有数据，而标准查询有

Solr dismax query returns no data, while standard query does
