限制cts的搜索扩展：element-value-search-Marklogic

Question

I am using cts:element-value-search to search document based on the parameter. While the query works fine I want it to search elements in immediate children only.

For Ex. My document tree looks like this

document1.xml

<Person>
    <FirstName>Johnson</FirstName>
    <LastName>W</LastName>
    <EmailAddress>john@abc.com</EmailAddress>
    <Neighbour>
        <FirstName>Mathew</FirstName>
        <LastName>Long</LastName>
    </Neighbour>
</Person>

document2.xml

<Person>
    <FirstName>Mathew</FirstName>
    <LastName>W</LastName>
    <EmailAddress>john@abc.com</EmailAddress>
    <Neighbour>
        <FirstName>Anderson</FirstName>
        <LastName>Long</LastName>
    </Neighbour>
</Person>

and my query is

cts:search(
  /Person,
  cts:and-query((
      cts:element-value-query(xs:QName("FirstName"), concat('*', "son", '*'), 
        ("wildcarded", "case-insensitive", "whitespace-sensitive", "punctuation-sensitive"))
  )),
  ()
)

This returns both the documents because for the first document it matches <FirstName>Johnson</FirstName>

and for the second document it matches

<FirstName>Anderson</FirstName>

which is at the lower level.

I do not want the second result and want the query to search at level 1 only.

Any help is appreciated.

Answer 1

You can scope sub-queries to particular container elements or properties, using cts:element-query , and cts:json-property-scope-query . Those will trim down sub-query matches to a particular ancestor.

cts:element-query(xs:QName('Person'), cts:element-value-query(xs:QName('Firstname', ...)) will not be enough however, as Neighbour/Firstname is also a descendant.

Simplest option is to use a path range index on Person/Firstname . That is by far the most straight-forward solution here.

HTH!
