我正在尽一切努力解决这个问题。
我有一个带有搜索功能的简单应用程序。当我搜索带有重音符号的单词时,搜索工作正常,但是如果我搜索不带重音符号的单词,则结果为空。
我阅读了Tire和Elasticsearch的文档,但不知道发生了什么
class Article < ActiveRecord::Base
attr_accessible :description, :title, :user_id
belongs_to :user
include Tire::Model::Search
include Tire::Model::Callbacks
mapping do
indexes :_id, index: :not_analyzed
indexes :title, analyzer: 'snowball', boost: 100
indexes :description, analyzer: 'snowball'
end
def self.search(params)
tire.search(page: params[:page], per_page: 10) do
query { string params[:q], default_operator: "AND" } if params[:q].present?
end
end
end
在贝娄,我尝试使用asiifolding,但是没有用。
class Article < ActiveRecord::Base
attr_accessible :description, :title, :user_id
include Tire::Model::Search
include Tire::Model::Callbacks
tire.settings :index => {
:analysis => {
:analyzer => {
:index_analyzer => {
:tokenizer => "whitespace",
:filter => ["asciifolding", "lowercase", "snowball"]
},
:search_analyzer => {
:tokenizer => "whitespace",
:filter => ["asciifolding", "lowercase", "snowball"]
}
},
:filter => {
:snowball => {
:type => "snowball",
:language => "Portuguese"
}
}
}
}
mapping do
indexes :_id, index: :not_analyzed
indexes :title, analyzer: 'snowball', boost: 100
indexes :description, analyzer: 'snowball'
end
def self.search(params)
tire.search(page: params[:page], per_page: 10) do
query { string params[:q], default_operator: "AND" } if params[:q].present?
end
end
end
我在Chrome上使用Sense进行测试,映射和所有配置都可以!
发生了什么???
谢谢
最佳答案
您必须使用在索引中指定的分析器。您当前正在使用“雪球”分析器来进行标题和描述,而不会进行Asciifolding:
mapping do
indexes :_id, index: :not_analyzed
indexes :title, analyzer: 'snowball', boost: 100
indexes :description, analyzer: 'snowball'
end
改为这样做
mapping do
indexes :_id, index: :not_analyzed
indexes :title, analyzer: :index_analyzer, boost: 100
indexes :description, analyzer: :index_analyzer
end
假设您要使用query_analyzer。然后,当您要搜索时,请使用其他分析器:
tire.search(page: params[:page], per_page: 10) do
query { string params[:q],
analyzer: :search_analyzer,
default_operator: "AND" } if params[:q].present?
end
