Retrieves a list of distinct values for a given field in all items that match a query, without duplicates.
As with the Query Data Items endpoint, this endpoint retrieves items based on the filtering, sorting, and paging preferences you provide.
However, the Query Distinct Values endpoint doesn't return all of the full items that match the query.
Rather, it returns all unique values of the field you specify in fieldName
for items that match the query.
If more than one item has the same value for that field, that value appears only once.
For more details on using queries, see API Query Language.
You can only call this method when authenticated as a Wix app or Wix user identity.
