輪胎::搜索:: SearchRequest關於utf8的錯誤信息關於utf8的錯誤

Question

我正試圖在我的rails應用程序中使用Tire實現ElasticSearch。我做了一個非常基本的設置：

country.rb 
class Country < ActiveRecord::Base 
    attr_accessible :name 

    include Tire::Model::Search 
    include Tire::Model::Callbacks 
end 

home.html.erb 
<%= form_tag '/pages/search', :method => 'get' do %> 
    <p> 
    <%= text_field_tag :query, params[:query] %> 
    <%= submit_tag "Search", name: nil %> 
    </p> 
<% end %> 

pages_controller.rb 
class PagesController < ApplicationController 
    def search 
     @countries = Country.search(params) 
    end 
end 

和我得到一個錯誤說：

400 : {"error":"SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[wy5c-7SwS2q0fXPjUg0gYg][countries][3]: SearchParseException[[countries][3]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"query_string\":{\"query\":{\"utf8\":\"\\u2713\",\"query\":\"C\",\"controller\":\"pages\",\"action\":\"search\"}}},\"size\":10}]]]; nested: QueryParsingException[[countries] [query_string] query does not support [utf8]]; }{[wy5c-7SwS2q0fXPjUg0gYg][countries][2]: SearchParseException[[countries][2]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"query_string\":{\"query\":{\"utf8\":\"\\u2713\",\"query\":\"C\",\"controller\":\"pages\",\"action\":\"search\"}}},\"size\":10}]]]; nested: QueryParsingException[[countries] [query_string] query does not support [utf8]]; }{[wy5c-7SwS2q0fXPjUg0gYg][countries][1]: SearchParseException[[countries][1]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"query_string\":{\"query\":{\"utf8\":\"\\u2713\",\"query\":\"C\",\"controller\":\"pages\",\"action\":\"search\"}}},\"size\":10}]]]; nested: QueryParsingException[[countries] [query_string] query does not support [utf8]]; }{[wy5c-7SwS2q0fXPjUg0gYg][countries][0]: SearchParseException[[countries][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"query_string\":{\"query\":{\"utf8\":\"\\u2713\",\"query\":\"C\",\"controller\":\"pages\",\"action\":\"search\"}}},\"size\":10}]]]; nested: QueryParsingException[[countries] [query_string] query does not support [utf8]]; }{[wy5c-7SwS2q0fXPjUg0gYg][countries][4]: SearchParseException[[countries][4]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"query_string\":{\"query\":{\"utf8\":\"\\u2713\",\"query\":\"C\",\"controller\":\"pages\",\"action\":\"search\"}}},\"size\":10}]]]; nested: QueryParsingException[[countries] [query_string] query does not support [utf8]]; }]","status":400} 

有人能看到什麼，我在這裏失蹤？非常感謝所有幫手！

試試這個：

def search 
    @countries = Country.search(params[:query]) 
end
