Marklogic附加查询和可搜索表达式问题

我的选项文件中既有

可搜索表达式

也有

附加查询

。。在我的

附加查询中

我有

cts字段值查询

，当我有这个查询时，我会得到空结果，即使我知道有文档同时匹配

可搜索表达式

和

附加查询

。。当我取出

cts:field-value查询

时，结果与预期一致。。我包括选项文件和

xdmp:query计划

。。我不明白为什么这个问题

let $options :=

let $q := '"pancreatic cancer"'


return
search:search($q, $options)

查询计划显示，在这两种情况下，片段都是从索引中选择的，因此我认为您的字段值查询确实匹配某些内容。它们通过过滤被排除

这可能是因为你的搜索表达式。它指向信封深处的一个非常特定的元素，字段的值可能来自该路径之外的元素

如果您试图影响搜索片段，我建议使用

转换结果

和

首选匹配

功能，而不是可搜索表达式。仅对可搜索表达式使用高级元素，如/es:envelope/es:raw或/es:envelope/es:instance，或者根本不使用

嗯

您所在领域的配置是什么？如果只执行字段值查询（而不执行其他查询），会发生什么情况？字段的配置是什么？当您仅执行字段值查询（而不执行其他查询）时会发生什么情况？您的意思是，如果我将

可搜索表达式

与

附加查询

一起使用，则字段应位于

可搜索表达式

内？在我的例子中，字段指向的路径不在

可搜索表达式中，因此问题出在哪里？如何实现当用户搜索字符串（无约束）时，搜索需要在xpath集合中执行。在所有
附加查询
约束之上？我通常会创建一个聚焦于所需路径的字段，并为此创建一个字段搜索约束，然后指示用户在搜索短语前面加上约束名称+冒号。。例如，
“胰腺癌”
变成了
标题栏：“胰腺癌”
。是的，我试图避免使用约束的方式，例如：）当search ws用于许多企业应用程序时，很难强制应用程序开发人员将此约束添加到他们的搜索字符串中，但当没有其他方法时，然后我们不得不假设你可以考虑在某个阶段以编程方式添加它。你甚至可以考虑做一种搜索扩展，其中非前缀的术语被扩展成一个查询或原始查询，一个增强的加权字段。在键入上面的内容时，我还记得你也可以为非前缀的术语实现自定义处理代码，也许这是一个很好的方法来扩展我的建议。有关详细信息，请参见：您所说的是，如果我将
