Description:
The fulltext search finds false positives in some cases.

How to repeat:
mysql> SELECT * FROM test1 JOIN test2 USING(`test1_id`) WHERE MATCH (test1.name,
 test2.name) AGAINST('xxfoo' IN BOOLEAN MODE);
+----------+-------+----------+----------+-------+
| test1_id | name  | test2_id | test1_id | name  |
+----------+-------+----------+----------+-------+
|        1 | data1 |        1 |        1 | xxfoo |
|        1 | data1 |        2 |        1 | xxbar |
|        1 | data1 |        3 |        1 | xxbuz |
+----------+-------+----------+----------+-------+
3 rows in set (0.00 sec)

Expected was only the first line, not all three.

(I'll attach the table dump as a file)
