我正在使用tire gem从我的Rails应用程序访问弹性搜索。我的代码生成以下查询,根据我对docs for sort的理解是正确的:
[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.elasticsearch.search.SearchParseException: [tweets][3]: query[ConstantScore(*:*)],from[-1],size[-1]: Parse Failure [Failed to parse source [{
"query": {
"match_all": {
}
},
"sort": [
{
"author": "asc"
}
],
"filter": {
"terms": {
"entities_ids": [
"10"
]
}
},
"size": 10,
"from": 0
}]]
生成此方法的方法如下所示:
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
端
我完全不知道为什么这不起作用。

我在排序方面遇到了类似的问题......取决于你如何索引该字段。如果它是一个令牌化的字符串你可能会挣扎相反,您可以使用多字段而不是分析它,或者您可以使用基于_source的_script排序:
{ "query": {
"query_string": {
"query": "something or other"
} }, "sort": {
"_script": {
"script": "_source.contentLegend",
"type": "string",
"order": "desc"
} } }
希望有所帮助!
