Marklogic附加查询与可搜索表达式问题

  •  0
  • Ravi  · 技术社区  · 6 年前

    我两样都有 searchable-expression additional-query 在我的选项文件中。。在我的 附加查询 我有 cts-field-value-query 当我得到这个时,我得到的结果是空的,尽管我知道有些文档两者都匹配 可搜索表达式 附加查询 .. 当我取出 cts:field-value-query 结果如期而至。。我包括选项文件和 xdmp:query-plan .. 我不明白为什么这个问题

    let $options :=
    <options xmlns="http://marklogic.com/appservices/search">
        <additional-query>
             <cts:and-query xmlns:cts="http://marklogic.com/cts">
                <cts:collection-query>
                    <cts:uri>OncoWatch</cts:uri>
                </cts:collection-query>
                 <cts:field-value-query>
                    <cts:field>wos_doctype</cts:field>
                    <cts:text>Article</cts:text>
                    <cts:text>Review</cts:text>
                </cts:field-value-query>
            </cts:and-query>
        </additional-query>
        <searchable-expression xmlns:es="http://marklogic.com/entity-services"
                               xmlns:wos_dps="http://clarivate.com/schema/wok5.27/public/FullRecord">
          /es:envelope/es:raw/wos_dps:REC/wos_dps:static_data/wos_dps:summary/wos_dps:titles/wos_dps:title
        </searchable-expression>
        <term>
            <term-option>case-insensitive</term-option>
            <term-option>punctuation-insensitive</term-option>
            <term-option>whitespace-insensitive</term-option>
            <term-option>wildcarded</term-option>
        </term>
        <return-plan>true</return-plan>
    </options>
    
    let $q := '"pancreatic cancer"'
    
    
    return
    search:search($q, $options)
    

    xdmp计划如下

    查询计划显示,在这两种情况下,片段都是从索引中选择的,因此我认为字段值查询确实匹配了某些内容。它们被过滤排除在外。

    那可能是因为你的可搜索表达式。它指向信封深处的一个非常特定的元素,而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 transform-results preferred-matches 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。

    啊!
