1、問題

示例數據：

{"id":"123456","title":"倚天屠龍記","author":"金庸" }

查詢示例：

GET article/_search {"query": {"match_phrase": {"author": "禁用"}} } 按上述查詢語句能把“金庸”相關的文章搜出來，因為搜索時回把漢字轉拼音，轉換后的拼音跟“金庸”的拼音一致，所以可以召回。

2、解決思路

將搜索分詞器與索引分詞器分開，搜索分詞器漢字轉拼音功能取消，這樣就不會搜索出同音字的內容。

將如下屬性設置為false. "keep_first_letter": false, "keep_separate_first_letter": false, "keep_full_pinyin": false,

3、修改后結果

搜"jin庸“可以搜出結果

搜”jin用“搜不出結果

4、索引定義

PUT article {"mappings": {"properties": {"id": {"type": "keyword"},"title": {"type": "text","fields": {"pinyin": {"type": "text","analyzer": "pinyin_analyzer","search_analyzer": "pinyin_search_analyzer"}},"analyzer": "ik_analyzer"},"author": {"type": "text","fields": {"pinyin": {"type": "text","analyzer": "pinyin_analyzer","search_analyzer": "pinyin_search_analyzer"}},"analyzer": "ik_analyzer"}}},"settings": {"index": {"number_of_shards": "1","analysis": {"filter": {"pinyin_filter": {"type": "pinyin","keep_joined_full_pinyin": "true","lowercase": "true","keep_original": "true","remove_duplicated_term": "true","keep_separate_first_letter": "true","limit_first_letter_length": "30","keep_full_pinyin": "true"},"pinyin_search_filter": {"type": "pinyin","lowercase": true,"keep_first_letter": false,"keep_separate_first_letter": false,"keep_full_pinyin": false,"keep_original": false,"limit_first_letter_length": 30,"keep_separate_chinese": true}},"char_filter": {"tsconvert": {"convert_type": "t2s","type": "stconvert"}},"analyzer": {"pinyin_analyzer": {"filter": ["pinyin_filter","lowercase"],"tokenizer": "standard"},"pinyin_search_analyzer": {"filter": ["pinyin_search_filter","lowercase"],"tokenizer": "standard"},"ik_analyzer": {"filter": ["lowercase"],"char_filter": ["tsconvert"],"type": "custom","tokenizer": "ik_smart"}}},"number_of_replicas": "0"}} }
