Question

我使用MySQL 5.5.9和MySQL 5.5.16以及mysqlse rev 2973

以下是狮身人面像查询：

SELECT
    id
FROM sphinx_search t
WHERE `query` = 'mode=extended2;
maxmatches=1000000;
query=@site_id,"0acd771ae618e89097564494af8bb838";
filter=search_engine_id,5;
limit=100; offset=0;
index=keywords_idx;
sort=extended:keyword_ord ASC;';

这是MySQL堆栈跟踪：

where mysqld died. If you see no messages after this, something went
terribly wrong...

我没有足够的代表直接评论我不想提供这个作为答案，但我认为这可能会导致你的问题或导致这个问题，是否有一个特殊的原因你有1,000,000最大匹配？见：http://sphinxsearch.com/docs/1.10/conf-max-matches.html

你要求sphinx为你得到一些东西，然后过滤掉它们中的100万个并对它们进行排序/排序然后只处理这100万个结果中的前100个......
