我在 rails 4 应用程序中使用轮胎和 mongoid。
class Agent
include Mongoid::Document
include Mongoid::Timestamps
include Mongoid::Taggable
include Tire::Model::Search
include Tire::Model::Callbacks
...
mapping do
indexes :id, index: :not_analyzed
indexes :name, type: 'string', analyzer: 'pattern'
indexes :tags_array, type: 'string', analyzer: 'pattern'
end
...
def self.search(params)
tire.search(load: true) do
query do
string "name:#{params}"
string "tags_array:#{params}"
end
end
end
...
有4个代理
Agent.all.collect(&:tags)
=> ["pune", "pune", "press", "pune press"]
Agent.all.collect(&:name)
=> ["agent smith", "first", "second", "third"]
我有3个问题
1）第一个问题是代理不能通过“名称”搜索。
results = Agent.search('first')
=> #<Tire::Results::Collection:0xb26dc4c @response={"took"=>1, "timed_out"=>false, "_shards"=>{"total"=>5, "successful"=>5, "failed"=>0}, "hits"=>{"total"=>0, "max_score"=>nil, "hits"=>[]}}, @options={:load=>true, :size=>10}, @time=1, @total=0, @facets=nil, @max_score=0.0, @wrapper=Tire::Results::Item>
results.results
=> []
2）第二个问题是 mongoid 给出错误，指定具有指定 id 的对象不存在。如果我根据标签搜索
results = Agent.search('press')
=> #<Tire::Results::Collection:0xb296da4 @response={"took"=>1, "timed_out"=>false, "_shards"=>{"total"=>5, "successful"=>5, "failed"=>0}, "hits"=>{"total"=>2, "max_score"=>0.30685282, "hits"=>[{"_index"=>"agents", "_type"=>"agent", "_id"=>"{\"$oid\"=>\"521da715f94adc957d000005\"}", "_score"=>0.30685282, "_source"=>{"name"=>"second", "tags_array"=>["press"]}}, {"_index"=>"agents", "_type"=>"agent", "_id"=>"{\"$oid\"=>\"521da715f94adc957d000004\"}", "_score"=>0.19178301, "_source"=>{"name"=>"third", "tags_array"=>["pune press"]}}]}}, @options={:load=>true, :size=>10}, @time=1, @total=2, @facets=nil, @max_score=0.30685282, @wrapper=Tire::Results::Item>
results.results
Mongoid::Errors::DocumentNotFound:
Problem:
Document(s) not found for class Agent with id(s) {"$oid"=>"521da715f94adc957d000005"}, {"$oid"=>"521da715f94adc957d000004"}.
Summary:
When calling Agent.find with an id or array of ids, each parameter must match a document in the database or this error will be raised. The search was for the id(s): {"$oid"=>"521da715f94adc957d000005"}, {"$oid"=>"521da715f94adc957d000004"} ... (2 total) and the following ids were not found: {"$oid"=>"521da715f94adc957d000005"}, {"$oid"=>"521da715f94adc957d000004"}.
Agent.all.collect(&:id)
=> ["521da715f94adc957d000007", "521da715f94adc957d000006", "521da715f94adc957d000005", "521da715f94adc957d000004"]
3）如果我重新索引代理对象，弹性搜索中的 id 与 mongodb 对象 id 完全不同
Agent.index_name
=> "agents"
Tire.index('agents').delete
=> true
Agent.import
=> #<Tire::Model::Import::Strategy::Mongoid:0xb2dad9c @klass=Agent, @options={:per_page=>1000}, @index=#<Tire::Index:0xb2dabe4 @name="agents", @response=#<Tire::HTTP::Response:0xb30c4b4 @body="{\"took\":630,\"items\":[{\"create\":{\"_index\":\"agents\",\"_type\":\"agent\",\"_id\":\"h0k78SupT9GGTT3I6qV3Bw\",\"_version\":1,\"ok\":true}},{\"create\":{\"_index\":\"agents\",\"_type\":\"agent\",\"_id\":\"LuJMwJSFRquezRUc1HUpEg\",\"_version\":1,\"ok\":true}},{\"create\":{\"_index\":\"agents\",\"_type\":\"agent\",\"_id\":\"gE6MreF8T4ePdD8lqutSJQ\",\"_version\":1,\"ok\":true}},{\"create\":{\"_index\":\"agents\",\"_type\":\"agent\",\"_id\":\"4azbinLjSO2LuRXn9-WYtg\",\"_version\":1,\"ok\":true}}]}", @code=200, @headers={:content_type=>"application/json; charset=UTF-8", :content_length=>"426"}>>>
results = Agent.search('press')
=> #<Tire::Results::Collection:0xb31bcac @response={"took"=>5, "timed_out"=>false, "_shards"=>{"total"=>5, "successful"=>5, "failed"=>0}, "hits"=>{"total"=>2, "max_score"=>1.0, "hits"=>[{"_index"=>"agents", "_type"=>"agent", "_id"=>"gE6MreF8T4ePdD8lqutSJQ", "_score"=>1.0, "_source"=>{"name"=>"second", "tags_array"=>["press"]}}, {"_index"=>"agents", "_type"=>"agent", "_id"=>"4azbinLjSO2LuRXn9-WYtg", "_score"=>0.19178301, "_source"=>{"name"=>"third", "tags_array"=>["pune press"]}}]}}, @options={:load=>true, :size=>10}, @time=5, @total=2, @facets=nil, @max_score=1.0, @wrapper=Tire::Results::Item>
results.results
=>Mongoid::Errors::DocumentNotFound:
Problem:
Document(s) not found for class Agent with id(s) gE6MreF8T4ePdD8lqutSJQ, 4azbinLjSO2LuRXn9-WYtg.
我是否正确定义了映射？用户应该能够根据代理名称或/和标签进行搜索。部分名称也应该被允许。
==更新
由于 localhost:9200/_mapping?pretty=1 而从 elasticsearch 映射
