限制cts:搜索设置xml元素的数量

Question

我有一个cts:query，我想将cts:query限制为只搜索一些xml。如果不创建任何字段索引或修改我的cts:query，这是可能的，因为我的cts:query非常大。当我这么做的时候

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，如下所示。我得到的表达是无法搜索的。如何做到这一点?..为了完成我的代码，下面是我的cts:query，下面只是一个示例，它要大得多的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("iv", ("case-insensitive", "wildcarded"))
                )))

要回答核心问题，可以使用cts:元素查询将查询限制为特定元素。

您的查询有很大的优化空间。我不认为它会相对于大型数据集进行扩展。我强烈建议您拥有与之联系的任何MarkLogic资源，查看您想要做的事情，并评估您的方法。
