Question

在调用这样的查询时，我无法找到任何结果：

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

但是调用这样的查询：

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

按预期查找9份文件。

我尝试了各种各样的东西（比如qildcard：：，但无济于事。）

如果有人能指出我的问题或文件，可能会解释我的错误。

如果重要，schema.xml如下：

Answer 1

得到解决方案，对于一些我不知道的原因，除非我们定义哪个字段应该用于过滤，否则q = king不起作用，在我的情况下：

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

PS

当然“标题：”也应该省略。我没有在原始问题中提及它，但我在查询中尝试使用和不使用它。

Solr dismax查询不返回任何数据，而标准查询执行
