[mikereiche]

It was removed here :

A customer was using it for:

criteriaBuild.append("SELECT META(ord).id AS __id, META(ord).cas AS __cas, "
                    + documentFieldsToSelect + " FROM `order` ord"
                    + unnest.toString() + " WHERE ord.javaClass='com.pepsico.och.orderstore.domain.Order'"
                    + criteria
                    + constraintAppend);
propOrders = couchbaseTemplate.findByQuery(Order.class).matching(new StringQuery(criteriaBuild.toString())).all();
