1. 自定义分词器

ES如何支持拼音和中文分词 ？

自定义分词器 支持拼音和中文分词

PUT /jd_goods{"settings": {"analysis": {"analyzer": {"ik_smart_pinyin": {"type": "custom","tokenizer": "ik_smart","filter": ["my_pinyin", "word_delimiter"]},"ik_max_word_pinyin": {"type": "custom","tokenizer": "ik_max_word","filter": ["my_pinyin", "word_delimiter"]}},"filter": {"my_pinyin": {"type" : "pinyin","keep_separate_first_letter" : true,"keep_full_pinyin" : true,"keep_original" : true,"limit_first_letter_length" : 16,"lowercase" : true,"remove_duplicated_term" : true}}}}}

2. 映射模型

重新指定文档类型映射拼音分词类型

POST /jd_goods/_mapping{"properties": {"title": {"type": "text","analyzer": "ik_max_word_pinyin","search_analyzer": "ik_smart_pinyin"},"desc": {"type": "text","analyzer": "ik_max_word_pinyin","search_analyzer": "ik_smart_pinyin"},"img": {"type": "text"},"price": {"type": "text"}}}

1.和2.可以合并为下面这一条命令

PUT /jd_goods{"settings": {"analysis": {"analyzer": {"ik_smart_pinyin": {"type": "custom","tokenizer": "ik_smart","filter": ["my_pinyin", "word_delimiter"]},"ik_max_word_pinyin": {"type": "custom","tokenizer": "ik_max_word","filter": ["my_pinyin", "word_delimiter"]}},"filter": {"my_pinyin": {"type" : "pinyin","keep_separate_first_letter" : true,"keep_full_pinyin" : true,"keep_original" : true,"limit_first_letter_length" : 16,"lowercase" : true,"remove_duplicated_term" : true}}}},"mappings": {"properties": {"title": {"type": "text","analyzer": "ik_max_word_pinyin","search_analyzer": "ik_smart_pinyin"},"desc": {"type": "text","analyzer": "ik_max_word_pinyin","search_analyzer": "ik_smart_pinyin"},"img": {"type": "text"},"price": {"type": "text"}}}}
