限制 cts:search 以设置 xml 个元素的数量

Question

我有一个 cts:query，我想限制我的 cts:query 只搜索一些 xml 元素。这是否可以在不创建任何字段索引或修改我的 cts:query 的情况下实现，因为我的 cts:query 非常大......当我这样做时

cts:search((
        //es:raw/wos_dps:REC/wos_dps:static_data/wos_dps:summary/wos_dps:titles/wos_dps:title,
        //es:raw/wos_dps:REC/wos_dps:static_data/ wos_dps:fullrecord_metadata/ wos_dps:abstracts/ wos_dps:abstract
       )
      , 
      $q, 
      ('unfiltered'))[1 to 10]

其中 $q 是我的 cts:query，如下例所示。我得到的表达式是无法搜索的..如何实现这个？..只是为了完成我的代码，下面是我的 cts:query ，下面只是一个示例，它更大 cts:query :)

cts:and-query(
          (
           cts:or-query(
           (
             cts:near-query(
              (
                cts:or-query((
                    cts:word-query("Guideline", ("case-insensitive", "punctuation-insensitive", "whitespace-insensitive", "wildcarded")),
                    cts:word-query("guidelines", ("case-insensitive", "punctuation-insensitive", "whitespace-insensitive", "wildcarded"))
                   )
                  )
                ,
                cts:or-query((
                    cts:word-query("clinical", ("case-insensitive", "punctuation-insensitive", "whitespace-insensitive", "wildcarded")),
                    cts:word-query("practice", ("case-insensitive", "punctuation-insensitive", "whitespace-insensitive", "wildcarded")),
                    cts:word-query("adherence", ("case-insensitive", "punctuation-insensitive", "whitespace-insensitive", "wildcarded"))         
                   )
                  )
              )
             , 
             4,
             ('unordered'))
             ,
               cts:near-query((
                cts:word-query("phase", ("case-insensitive", "wildcarded")),
                cts:or-query((
                  cts:word-query("0", ("case-insensitive", "wildcarded")),
                  cts:word-query("1", ("case-insensitive", "wildcarded")),
                  cts:word-query("2", ("case-insensitive", "wildcarded")),
                  cts:word-query("3", ("case-insensitive", "wildcarded")),
                  cts:word-query("4", ("case-insensitive", "wildcarded")),
                  cts:word-query("i", ("case-insensitive", "wildcarded")),
                  cts:word-query("ii", ("case-insensitive", "wildcarded")),
                  cts:word-query("iii", ("case-insensitive", "wildcarded")),
                  cts:word-query("iv", ("case-insensitive", "wildcarded"))
                )))
               , 
               0, 
               ('unordered')),
             cts:near-query((
               cts:or-query((
                 cts:word-query("phase2*", ("case-insensitive", "wildcarded")),

                 cts:word-query("phaseiv*", ("case-insensitive", "wildcarded"))
               )),
               cts:or-query((

               ))
               ), 
               1, 
               ('unordered')),
           )
          ),
           cts:collection-query(("http://xxxx/entity/wos/article")),
           cts:element-attribute-value-query((xs:QName(xs:QName("wos_dps:pub_info"))),
                  (xs:QName("wos_dps:pubyear")),
                  "2017")
          )
          , 
          ("unordered"))

要回答您的核心问题，您可以使用 cts:element-query 将查询限制为特定元素。

您的查询有很大的优化空间。我不认为它会针对大型数据集进行扩展。我强烈建议您拥有任何您接触过的 MarkLogic 资源，看看您正在尝试做什么并评估您的方法。
