问题描述
SELECT * FROM sphinx.articles WHERE query='something everything;mode=all';

| 40391221 | 2 | something everything;mode=all |
+----------+--------+-------------------------------+
20 rows in set (0.233 sec)
并通过
获得总结果SHOW STATUS LIKE 'Sphinx_total_found';
+--------------------+--------+
| Variable_name | Value |
+--------------------+--------+
| Sphinx_total_found | 356179 |
+--------------------+--------+
1 row in set (0.004 sec)
我想知道是否有可能获得 Sphinx 索引的所有可能组合？
例如，获取两个关键字的所有组合的结果数为
+-------------------+-------------------------------+
| query | total_results |
+-------------------+-------------------------------+
| something everything;mode=all | 58844 |
| word1 word2;mode=all | 11 |
| word1 word3;mode=all | 234 |
| word2 word3;mode=all | 663 |
| word2 word4;mode=all | 9115 |
+-------------------+-------------------------------+
我理解Sphinx是通过查询中给定的关键字动态查找结果的，但是理论上所有索引的关键字都是已知的，我们可以进行组合。但是，如果我们单独进行查询，则太慢了。
