MarkLogic - get great results without using Xpath

Question

I use the query below to retrieve various values ​​from XML files stored in a collection in MarkLogic. The collection contains more than 40 thousand files.

When a query is executed, the results take a long time. Is there a better way to optimize the query below or any other use cases for this query without XPath.

XQUERY:

fn:distinct-values(fn:collection(collectionName)//caseml/case[@jur eq in]/@year)

XML input example:

<?xml version="1.0" encoding="UTF-8"?>
<caseml>
  <case jur="in" series="mlj" volume="1" year="2016" startpage="129">
    <p num="y" pnum="22">
      <text>
        In view of the aforesaid discussion, we find the writ petition completely devoid
        of any merit and accordingly, we dismiss the same, leaving the parties to bear their
        own costs.
      </text>
    </p>
  </case>
</caseml>

The above XQuery works, but you need to get results faster.
