I have a list with column who have managed data property and I would like that a user can search based on that managed data property. For example if I have this hierarchy in my Term Store
If user would enter North America it would search the list and give all result tagged as North America ,Canada and USA. That mean I want result set with Parent terms and all the child terms.
How can I achieve that?
I have used REST and its giving me only results tagged with child terms?
Do I need to make a web part ? Should I use CAML ?
I am lost.
