elasticsearch模糊查询为什么搜不到啊, 我用的就是ngram啊？

我要实现模糊查询, 建立了如下的索引

PUT myidx1 { "_all": { "enabled": false }, "settings": { "analysis": { "tokenizer": { "my_ngram": { "type": "nGram", "min_gram": "1", "max_gram": "20", "token_chars": [ "letter", "digit" ] } }, "analyzer": { "mylike": { "tokenizer": "my_ngram", "filter": [ "lowercase" ] } } } }, "mapping": { "mytype": { "dynamic": false, "properties": { "name": { "type": "string", "analyzer": "mylike" } } } } }

测试一个

POST myidx1/_analyze { "analyzer": "mylike", "text": "文档3-aaa111" }

结果如下,

{"tokens": [ {"token": "文","start_offset": 0,"end_offset": 1,"type": "word","position": 0 }, {"token": "文档","start_offset": 0,"end_offset": 2,"type": "word","position": 1 }, {"token": "文档3","start_offset": 0,"end_offset": 3,"type": "word","position": 2 }, {"token": "档","start_offset": 1,"end_offset": 2,"type": "word","position": 3 }, {"token": "档3","start_offset": 1,"end_offset": 3,"type": "word","position": 4 }, {"token": "3","start_offset": 2,"end_offset": 3,"type": "word","position": 5 }, {"token": "a","start_offset": 4,"end_offset": 5,"type": "word","position": 6 }, {"token": "aa","start_offset": 4,"end_offset": 6,"type": "word","position": 7 }, {"token": "aaa","start_offset": 4,"end_offset": 7,"type": "word","position": 8 }, {"token": "aaa1","start_offset": 4,"end_offset": 8,"type": "word","position": 9 }, {"token": "aaa11","start_offset": 4,"end_offset": 9,"type": "word","position": 10 }, {"token": "aaa111","start_offset": 4,"end_offset": 10,"type": "word","position": 11 }, {"token": "a","start_offset": 5,"end_offset": 6,"type": "word","position": 12 }, {"token": "aa","start_offset": 5,"end_offset": 7,"type": "word","position": 13 }, {"token": "aa1","start_offset": 5,"end_offset": 8,"type": "word","position": 14 }, {"token": "aa11","start_offset": 5,"end_offset": 9,"type": "word","position": 15 }, {"token": "aa111","start_offset": 5,"end_offset": 10,"type": "word","position": 16 }, {"token": "a","start_offset": 6,"end_offset": 7,"type": "word","position": 17 }, {"token": "a1","start_offset": 6,"end_offset": 8,"type": "word","position": 18 }, {"token": "a11","start_offset": 6,"end_offset": 9,"type": "word","position": 19 }, {"token": "a111","start_offset": 6,"end_offset": 10,"type": "word","position": 20 }, {"token": "1","start_offset": 7,"end_offset": 8,"type": "word","position": 21 }, {"token": "11","start_offset": 7,"end_offset": 9,"type": "word","position": 22 }, {"token": "111","start_offset": 7,"end_offset": 10,"type": "word","position": 23 }, {"token": "1","start_offset": 8,"end_offset": 9,"type": "word","position": 24 }, {"token": "11","start_offset": 8,"end_offset": 10,"type": "word","position": 25 }, {"token": "1","start_offset": 9,"end_offset": 10,"type": "word","position": 26 }] }

这个结果是不是就证明, 我可以用a搜索, 用1也可以搜到????
那么测试一下
插入数据

POST myidx1/mytype/_bulk { "index": { "_id": 4}} { "name": "文档3-aaa111" } { "i优艾设计网_设计圈ndex": { "_id": 5}} { "name": "yyy111"} { "index": { "_id": 6}} { "name": "yyy111"}

然后查不到呢

GET myidx1/mytype/_search { "query": { "match": { "name": "1" } } }

结果如下:

{"took": 10,"timed_out": false,"_shards": { "total": 5, "successful": 5, "failed": 0},"hits": { "total": 0, "max_score": null, "hits": []} }

为什么, 这是为什么啊!!!!快崩溃了~
