perl – 带有Search :: ElasticSearch :: Scroll的ElasticSearch(search_context_missing_exception)

我正在使用Search :: Elasticsearch和Search :: Elasticsearch :: Scroll进行搜索并滚动到我的elasticsearch服务器.

在滚动过程中,对于某些查询,我在滚动搜索结果时看到下一个错误：

           },'type' => 'Missing'
},'Search::Elasticsearch::Error::Missing' );

我正在使用的代码是下一个(简化)：

# Retrieve scroll 
my $scroll = $self->getScrollBySignature($item);

# Retrieve all affected documents ids 
while (my @docs = $scroll->next(500)) {
    # Do stuff with @docs
}

函数getScrollBySignature具有下一个代码,以便调用elasticSearch

my $scroll = $self->{ELASTIC}->scroll_helper(
    index              => $self->{INDEXES},search_type        => 'scan',ignore_unavailable => 1,body               => {
        size  => $self->{PAGINATION},query => {
            filtered => {
                filter => {
                    bool => {
                        must => [{term => {signature_id => $item->{profileId}}},{terms => {channel_type_id => $type}}]
                    }
                }
            }
        }
    }
);

正如你所看到的,我正在做滚动而不传递滚动参数然后正如文档所说,滚动活着的时间是1分钟.

elasticSearch是一个由3个服务器组成的集群,以该错误结束的查询检索的文档超过5000个.

我的第一个解决方案是将滚动的生命周期更新为5分钟,并且没有出现错误.

问题是,正如我所知,每当我调用$scroll-> next()时,受影响的滚动生命周期会升级1m,那么如何才能接收这些与上下文相关的错误？

我做得不好吗？

谢谢你们.

解决方法

首先想到的是计时器没有更新.你检查过这个吗？例如,你可以每隔10秒进行一次查询,看看第6次查询是否会给你错误…
