我看过这篇文章:https://www.elastic.co/blog/you-complete-me 但是,它需要在客户端编写一些逻辑来创建多个"输入".有没有办法定义一个分析器(可能使用shingle或ngram/edge-ngram)来生成多个输入项？

这是我尝试过的(显然不起作用):

DELETE /products/
PUT /products/
{
    "settings": {
        "analysis": {
            "filter": {
                "autocomplete_filter": {
                    "type":"shingle",
                    "max_shingle_size":5,
                    "min_shingle_size":2
                }
            },
            "analyzer": {
                "autocomplete": {
                    "filter": [
                        "lowercase",
                        "autocomplete_filter"
                    ],
                    "tokenizer": "standard"
                }
            }
        }
    }, 
    "mappings": {
        "product": {
            "properties": {
                "name": {"type": "string"
                ,"copy_to": ["name_suggest"]
                }
                ,"name_suggest": {
                    "type": "completion",
                    "payloads": false,
                    "analyzer": "autocomplete"
                }
            }
        }
    }
}

PUT /products/product/1
{
    "name": "Apple iPhone 5"
}

PUT /products/product/2
{
    "name": "iPhone 4 16GB"
} …

我的网站是单页webapp.我正在使用我的实验ID加载实验代码:

<script src="//www.google-analytics.com/cx/api.js?experiment={@ js_settings.analytics.experimentid @}"></script>

加载完毕后,在我显示页面的那一刻,我通过调用执行以下操作的函数选择正确的模板:

ga('set', 'expId', experiment_id);
var variation = cxApi.getChosenVariation(experiment_id) || cxApi.chooseVariation();
cxApi.setChosenVariation(variation, experiment_id);
ga('set', 'expVar', variation);
ga('set', 'dimension1', variation);
ga('send', 'pageview');

现在,似乎cxApi.chooseVariation()总是返回0.到目前为止,205个会话中的100%被赋予默认变体(0).为什么？
