我在我的Rails应用程序中使用elasticsearch-rails gem来简化与Elasticsearch的集成。我正在尝试使用phonetic analysis plugin,因此我需要为索引定义自定义分析器和自定义过滤器。
为了使用soundex语音过滤器执行自定义分析,我尝试了这段代码,但它失败并显示异常消息:
[!!!]创建索引时出错:Elasticsearch :: Transport :: Transport :: Errors :: BadRequest [400] {“error”:“MapperParsingException [mapping [call_sentence]];嵌套:MapperParsingException [Analyzer [{tokenizer = standard,filter = [standard,lowercase,metaphoner]}]找不到字段[phonetic]];”, “状态”: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

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',
filter: ["standard", "lowercase", "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

好吧,我修改了elasticsearch.yml配置以包含语音分析器
