服务器配置 16G 内存， 500G 硬盘，分了 8G 给 ES 用。网站搭配 flask+nginx+mongodb+elasticsearch,最近 google webmaster 里老出现 500 和 502 错误，见前一个帖子 http://v2ex.com/t/247625#reply9 ，现在找到原因是 ES 全文搜索有错误，我在 ES 日志里看到不少这种搜索错误，请问是什么原因造成的？内存还是小吗？

wico77 OP @Zzzzzzzzz 你的意思是 query 查询的词后面有个'\'?
我使用 pyes ，获取查询词之后的语句是这样的： bt = QueryStringQuery(keyword.lower()) s = Search(bt) videos =conn.search(s, size=32, indices="exta",start=(page-1)*32) 请问传过去的查询如何修正？ |

@wico77 pyes 我没用过啊，那几个 python 的库选来选去，我们最后选了官方的 elasticsearch-dsl-py

@wico77 我没复现你的问题, 我猜是不是低版本 simplejson 导致的, 印象里以前 simplejson 确实有过 slash 问题, 先升级一下重启应用试试.
