Elasticsearch query time boosting produces result in inadequate order - elasticsearch

Question

The ES search result for the given search keyword one two three seems to be wrong after applying boost feature per keyword. Please help me modifying my "faulty" query in order to accomplish "expected result" below as I described. I'm on ES 1.7.4 with LUCENE 4.10.4
Boosting criteria -three is regarded as the most important keyword:
word - boost
---- -----
one 1
two 2
three 3
ES index content - just showing MySQL dump to make the post shorter
mysql> SELECT id, title FROM post;

14 rows in set (0.00 sec)
Expected ES query result - The user is searching for one two three. I'm not fussed about the order of equally scored records. I mean if record 6 and 13 switches places, I don't mind.
+----+-------------------+
| id | title | my scores for demonstration purposes
+----+-------------------+
| 6 | one two three | (1+2+3 = 6)
| 13 | one two three abc | (1+2+3 = 6)
| 7 | two three | (2+3 = 5)
| 14 | two three abc | (2+3 = 5)
| 5 | one three | (1+3 = 4)
| 4 | one two | (1+2 = 3)
| 12 | one two abc | (1+2 = 3)
| 3 | three | (3 = 3)
| 11 | three abc | (3 = 3)
| 2 | two | (2 = 2)
| 10 | two abc | (2 = 2)
| 1 | one | (1 = 1)
| 9 | one abc | (1 = 1)
| 8 | none | <- This shouldn't appear

Unexpected ES query result - Unfortunately, This is what I get.
