Question

我正在尝试计算复杂匹配查询的分数。例如：

if conditionA and conditionB and (conditionC or conditionD) 
then score = 10
else score = 0

这是我提出的解决方案：

let $idReq := cts:register(
  cts:and-query((
   cts:path-range-query("/person/name", "=", 'val1', ("score-function=linear", "collation=http://marklogic.com/collation//S1")),
   cts:path-range-query("/person/country", "=", 'country', ("score-function=linear", "collation=http://marklogic.com/collation//S1")),
   cts:or-query((
     cts:path-range-query("/person/city", "=", 'city', ("score-function=linear", "collation=http://marklogic.com/collation//S1")),
     cts:path-range-query("/person/school", "=", '', ("score-function=linear", "collation=http://marklogic.com/collation//S1"))
   ))
 ))
)
return
  cts:score(cts:search(fn:doc(), cts:registered-query($idReq, ("unfiltered"), 10)))

所有索引都存在，也是整理。

当我执行此注册查询时，我总是得到0分数。

我已经缩小了问题范围，可以通过组合cts来复制：使用cts注册：path-range-query。

let $query := cts:path-range-query("/person/name", "=", "val1", ("score-function=linear", "collation=http://marklogic.com/collation//S1"))
let $idReq := cts:register($query)
return 
  cts:score(
    cts:search(fn:doc(), 
      cts:registered-query($idReq,("unfiltered"), 10)
      (: $query :)
    )
  )

设置索引配置以进行测试：

import module namespace admin = "http://marklogic.com/xdmp/admin" at "/MarkLogic/admin.xqy";

let $dbid := xdmp:database("Documents")
let $config := 
  admin:database-add-range-path-index(
    admin:get-configuration(), $dbid, 
    admin:database-range-path-index(
      $dbid, "string", "/person/name",
      "http://marklogic.com/collation//S1",
      fn:false(), "ignore"))
return admin:save-configuration($config)

示例数据：

xdmp:document-insert(
  '/test/person1.xml',
  <person>
    <name>val1</name>
    <city>city</city>
    <country>country</country>
  </person>
)

如何获得已注册查询的分数
