Mar 20, 2018 · FIRST_ROWS is the historical version of FIRST_ROWS(n). And generally it should not be used. FIRST_ROWS(n) is "optimize for the first n rows using all the normal costing algorithms", whereas FIRST_ROWS is "optimizer for the first rows using a pre-defined set of rules that will force index use, nested loops, etc."

With the FIRST_ROWS(n) hint, the optimizer instructs the Text index to return rowids in score-sorted order when the cost of returning the top-N hits is lower. Without the hint, Oracle Database sorts the rowids after the Text index has returned all the rows in unsorted order that satisfy the CONTAINS predicate. Retrieving the entire result set this way takes time.
