我在我的Rails应用程序中使用
@L_404_0@ gem来简化与Elasticsearch的集成.我正在尝试使用
phonetic analysis plugin,所以我需要为我的索引定义自定义分析器和自定义过滤器.
我尝试了这段代码,以便使用soundex语音过滤器执行自定义分析,但它失败并显示异常消息：
[!!!] Error when creating the index: Elasticsearch::Transport::Transport::Errors::BadRequest
[400] {“error”:”MapperParsingException[mapping [call_sentence]]; nested: MapperParsingException[Analyzer [{tokenizer=standard,filter=[standard,lowercase,Metaphoner]}] not found for field [phonetic]]; “,”status”:400}
# Set up index configuration and mapping
#
settings index: { number_of_shards: 1,number_of_replicas: 0 } do
mapping do
indexes :text,type: 'multi_field' do
indexes :processed,analyzer: 'snowball'
indexes :phone,{analyzer: {
tokenizer: "standard",filter: ["standard","lowercase","Metaphoner"]
},filter: {
Metaphoner: {
type: "phonetic",encoder: "soundex",replace: false
}
}}
indexes :raw,analyzer: 'keyword'
end
end
end
解决方法
您也可以在设置调用中指定它：
settings index: {
number_of_shards: 1,number_of_replicas: 0,analysis: {
filter: {
Metaphoner: {
type: 'phonetic',encoder: doubleMetaphone,replace: true,}
},analyzer: {
phonetic_analyzer: {
tokenizer: 'standard',"Metaphoner"],}
}
}
} do
mapping do
indexes :text,type: 'multi_field' do
indexes :processed,analyzer: 'snowball'
indexes :phone,analyzer: 'phonetic_analyzer'
indexes :raw,analyzer: 'keyword'
end
end
end
