FIRST and LAST can be used with one argument and work similarly to MIN and MAX but they are implemented using a Top Hits aggregation and therefore can also operate on keyword fields. When a second argument is provided then they return the first/last value of the first arg when its values are ordered ascending/descending (respectively) by the values of the second argument. Currently because of the usage of a Top Hits aggregation FIRST and LAST cannot be used in the HAVING clause of a GROUP BY query to filter on the results of the aggregation. Closes: #35639 |
