Question

我正在MarkLogic上实现基于对象的智能框架，但我现在看不到哪个索引。

我创建了对象并使用rest扩展从提取到端点的（传感器）数据中提取对象。

服务器日志说：

2015-08-17 15：46：41.763信息：cluey-app：状态500： XDMP-ELEMRIDXNOTFOUND：cts：element-values（xs：QName（“obj：id”），（）， “核对= http://marklogic.com/collation/codepoint”， CTS：和查询（（CTS：收集查询（ “对象”）， cts：element-range-query（xs：QName（“obj：type”），“=”，“sensor”，（“collation = http://marklogic.com/collation/”），1）， cts：element-range-query（xs：QName（“scc：id”），“=”， xs：untypedAtomic（“rb-0041”），（），1）），（））） - 没有字符串元素范围 {http://marklogic.com/solutions/obi/object}类型的索引 http://marklogic.com/collation/

尝试创建对象的代码块是：

xquery version "1.0-ml";

    import module namespace obj = "http://marklogic.com/solutions/obi/object" at
      "/ext/obi/lib/object-service-lib.xqy",
      "/ext/obi/lib/object-lib.xqy";

    declare namespace sight= "http://klpd.nl/sight";
    declare namespace scc= "http://sensingclues.com/sccs";


    declare variable $source-id external;
    declare variable $result external;
    declare variable $merge external;

    for $object in $result/objects/element()
    let $type := obj:get-type-from-content($object)
    let $existing-object :=
      if ($merge) then
        cts:element-values(xs:QName("obj:id"), (), ("collation=http://marklogic.com/collation/codepoint"), cts:and-query((
          cts:collection-query("object"),
          obj:type-query($type),
          cts:element-range-query(xs:QName("scc:id"), "=", $object//scc:id)
        )))[1]
      else ()
    let $object-id :=
      if ($existing-object) then
        let $detail-id := obj:add-details($existing-object, $object, $source-id,()) (:hk empty workspace-id:)
        return $existing-object
      else
        obj:create-object($object, $source-id)[1]

    return <result id="{$object-id}" type="{$type}"/>
    ', (xs:QName('source-id'), $source-id, xs:QName('result'), $result, xs:QName('merge'), $merge),
    <options xmlns="xdmp:eval"><isolation>different-transaction</isolation></options>)

添加此特定任务的ml-config中的索引是：

    <!-- Cluey specific indexes -->
    <range-element-index>
      <scalar-type>string</scalar-type>
      <namespace-uri>http://sensingclues.com/sccs</namespace-uri>
      <localname>id</localname>
      <collation>http://marklogic.com/collation/</collation>
      <range-value-positions>false</range-value-positions>
      <invalid-values>reject</invalid-values>
    </range-element-index>
    <range-element-index>

      <collation>http://marklogic.com/collation/</collation>
      <range-value-positions>false</range-value-positions>
      <invalid-values>reject</invalid-values>
    </range-element-index>

问题：

我错过了什么指数？我使用错误的校对点吗？

缺少索引和整理

    <range-element-index>
      <scalar-type>string</scalar-type>

    </range-element-index>

Answer 1

Dave说 - 我的猜测是你在app服务器上运行查询默认为根目录排序，因此对obj：type的元素范围查询默认为根目录排序，但是index用于代码点排序规则。

Answer 2

看起来你错过了“obj：type”的索引。

<range-element-index>
  <scalar-type>string</scalar-type>
  <namespace-uri>http://marklogic.com/solutions/obi/object</namespace-uri>
  <localname>type</localname>
  <collation>http://marklogic.com/collation/</collation>
  <range-value-positions>false</range-value-positions>
  <invalid-values>reject</invalid-values>
</range-element-index>
