What sort of indexing I should use if I try to run the following query?
SELECT part_id FROM part WHERE dimen1 >= ? and dimen2 >= ? and dimen3 >= ? and dimen4 >= ? ORDER BY dimen1, dimen2,
dimen3,dimen4 LIMIT 100;
I tried creating index on the dimen1, dimen2, dimen3, and dimen4 columns,
but this dosn't help at all. The query plan I always get is sorting
followed by a seq scan.
Sort (cost=2822.86 rows=622 width=96) -> Seq Scan on part (cost=2822.86 rows=622 width=96)
Thanks
