   $property-name as xs:string*,
   $query as cts:query
) as cts:json-property-scope-query

Usage Notes

Enabling both the word position and element word position indexes will speed up query performance for many queries that use cts:json-property-scope-query. The position indexes enable MarkLogic Server to eliminate many false-positive results, which can reduce disk I/O and processing, thereby speeding the performance of many queries. The amount of benefit will vary depending on your data.

Example

(:
Given a database that has a JSON document as follows:
{"a":"aa","new":["array","content"],"b":["aa","bb"]}
:)
  cts:search(doc(),
    cts:json-property-scope-query(
      "a",
      "aa"))

  => .. relevance-ordered sequence of JSON documents (including
     the above document) with a property named "a" and some text value 
     anywhere within this property that includes the word or token "aa".
