Sorting 轮胎/弹性搜索:排序不工作
我正在使用从Rails应用程序访问弹性搜索。我的代码生成以下查询,据我所知是正确的:Sorting 轮胎/弹性搜索:排序不工作,sorting,elasticsearch,tire,Sorting,elasticsearch,Tire,我正在使用从Rails应用程序访问弹性搜索。我的代码生成以下查询,据我所知是正确的: [2013-08-09 15:06:08,538][DEBUG][action.search.type ] [Nitro] [tweets][3], node[INKC2ryGQ4Sx1qYP4qC-Og], [P], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@54daad1d] org.

生成此项的方法如下所示:
def Tweet.search_tweets(params = {})
Tweet.search(page: params[:page], per_page: params[:per_page]) do
if params[:query_string].present? || params[:sentiment].present? ||
(params[:start_date].present? && params[:end_date].present?)
query do
boolean do
if params[:query_string].present?
must { string params[:query_string], default_operator: "AND" }
end
if params[:sentiment].present?
must { term :sentiment, params[:sentiment]}
end
if params[:start_date].present? && params[:end_date].present?
must { string "created_at:[#{params[:start_date]} TO #{params[:end_date]}]"}
end
end
end
else
query do
all
end
end
if params[:entity_id].present?
filter :terms, entities_ids: [params[:entity_id]]
end
if params[:sort].present?
sort { by params[:sort][:by], params[:sort][:order] }
end
end
结束
我完全不知道为什么这不起作用。我在排序方面也有类似的问题。。。取决于您对该字段的索引方式。如果它是一个标记化的字符串,您可能会遇到困难。相反,您可以使用多字段而不是分析它,或者您可以使用基于_源的_脚本排序:
{ "query": {
"query_string": {
"query": "something or other"
} }, "sort": {
"_script": {
"script": "_source.contentLegend",
"type": "string",
"order": "desc"
} } }
希望对你有所帮助
