问题如下。我有索引哪个MySQL源包含4.5M +条目。 但count()查询在此索引中仅显示1.5M +条目。请参阅详细信息:
当我为此来源运行索引器时,我看到:
# indexer --rotate <index>

rotating indices: successfully sent SIGHUP to searchd (pid=29227).
它说&#34;收集 4558763 docs,552.5 MB&#34;。
另一方面,当我运行计数查询时,我得到了这个:
sphinxQL> select * from <index> limit 0; show meta;
Empty set (0.14 sec)
+---------------+---------+
| Variable_name | Value |
+---------------+---------+
| total | 1000 |
| total_found | 1570351 |
| time | 0.072 |
+---------------+---------+
3 rows in set (0.00 sec)
或此查询(相同结果):
sphinxQL> select 1 as d, count(*) c from <index> group by d;
+------+---------+
| d | c |
+------+---------+
| 1 | 1570351 |
+------+---------+
1 row in set (0.15 sec)
所以看起来狮身人面像只发现 1.5M + 条目。怎么可能?也许我错过了什么?
答案 0 :(得分:0)
添加到查询&#34;选项&#34;串。查询将是这样的:
从限制0选择* OPTION max_matches = 10000000
尝试这两个想法。
