1. Create a Structure, add a repeatable field "parent" and a nested sub-field "child".
2. Create a template for the previously created Structure
3. Create a web content from the Structure
   • Add two more "parent" fields by clicking on the plus sign
   • Add different values to the parents and children. E.g. p1, c1; p2, c2; p3, c3
   • Publish the Web Content
4. Add a Search portlet to a page
5. Try to search for the content you wrote into the fields

Result: If you are searching for p1, p2, p3 or c1, it shows the Web Content. Seaching for c2 or c3 shows no results.

Expected: Searching for p1, p2, p3, c1, c2 or c3 results the Web Content.
