版本:
CentOS - 6.4 (Final) Haystack - 2.1.0 ElasticSearch - 1.2.1 Java - 1.7.0_55 Django-cms - 2.3.1 pyelasticsearch - 0.6
我在CentOS机器的Django项目中使用ElasticSearch时遇到问题.我习惯在Ubuntu机器上配置Elasticsearch/Haystack,从来没有像这样的问题.
我收到此错误Parse Failure [No parser for element [y]]
,但我有一个空索引.我试图确切地知道错误的来源,所以我尝试了:
删除索引并再试一次(得到相同的错误)
尝试使用空索引(得到相同的错误)
安装/重新安装 - >清除并重新安装
我尝试使用较旧和较新的ES版本(0.90,1.2,1.1 ..)
检查JAVA版本
寻找版本不兼容 -
起初我以为错误是由索引的内容,我试图索引的数据引起的,但在删除/清除索引之后我仍然得到了同样的错误.
我试图在模板中显示一个空的查询集(因为我不知道还有什么试图找出问题所在)
附加信息
当我用python manage.py shell
和打开Django shell时
from haystack.query import SearchQuerySet SearchQuerySet() SearchQuerySet().all() SearchQuerySet().filter(content='any_text')
这种查询运行没有问题,如果没有找到任何内容则返回空查询集,或者如果找到某些内容则返回查询集.尝试在视图中使用该命令并将结果返回到模板时,我收到错误和问题.在shell中一切正常,如果索引为空则返回空查询集,如果索引有值则返回它必须返回的值

如果您需要任何其他信息来弄清楚这里发生的事情,请不要犹豫,我会尽快发布.
我想也许问题来自pyelasticsearch
.任何人都有类似的问题吗?

我尝试了另一件事,我在Ubuntu服务器上安装了ElasticSearch,并将查询从CentOS发送到Ubuntu.我是CMSPlugin
django-cms的索引模型,看起来插件的正文/文本包含一些特殊字符,Java或Elasticsearch尝试解析失败.这是第一个使ElasticSearch/Java崩溃的字符串\ud900\udc71\ud840\udc65y\u0000\ud900\udc74
.
我在python控制台中试过这个
c=u'\ud900\udc71\ud840\udc65y\u0000\ud900\udc74' print c
输出: y

我想知道CentOS上的Java是否有问题,我已经尝试将Java版本降级到1.6并且没有工作

现在我正在直接使用ElasticSearch,使用urllib2查询弹性搜索,避免使用Haystack.ElasticSearch完美地回答了问题(我必须管理JSON).我提出问题是Haystack如何生成或解析查询,因为当我尝试使用SearchQuerySet()
和制作类似于SearchQuerySet().filter(content='whatever')
使用shell或在视图中的内容时,ElasticSearch会因上述错误崩溃,但在执行时效果很好CURL

最后,我在不使用Haystack的情况下直接使用最后一个ElasticSearch.似乎问题是Haystack/pyelasticsearch如何格式化要发送给ES的查询,它无法解析编码并在每个请求中失败.
我没有找到任何解决方案,只是避免与Haystack合作,如果有人能指出解决方案会很棒,我也会发送电子邮件给Haystack的人,看看他们是否已经注意到这个问题.

如果有人在CentOS上配置了Haystack,我将不胜感激任何有关配置和软件版本的指南.我在CentOS上运行ElasticSearch但我直接通过ElasticSearch管理查询,完全忽略了Haystack
