我正在努力解决这个问题。
我有一个简单的app rails搜索。当我使用重音搜索某些内容时,搜索工作正常,但如果我搜索没有重音符号的单词,则结果为空。
我阅读了Tire和Elasticsearch的文档,但我不知道发生了什么
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
贝娄我尝试使用asciifolding,但它不起作用。
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,映射和所有配置都没问题!
发生了什么事?

您必须使用在索引中指定的分析器。您目前正在使用“雪球”分析器作为您的标题和描述,但不执行asciifolding:
mapping do
indexes :_id, index: :not_analyzed
indexes :title, analyzer: 'snowball', boost: 100
indexes :description, analyzer: 'snowball'
end
改为
mapping do
indexes :_id, index: :not_analyzed
indexes :title, analyzer: :index_analyzer, boost: 100
indexes :description, analyzer: :index_analyzer
end
假设您需要query_analyzer。然后,当您想要搜索时,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
