[medcl]

分词配置里面，把ngram去掉，重试

hi，medcl大神，我又来这边看pinyin了，请教您个问题，如果我想要通过pinyin进行正向搜索，应该怎么处理呢？比如，我想搜索 “我们来自**” “**是个大国”，我输入‘zg’ 就会把前面的搜出来，您明白这个意思了吗？就是说我想把正向的内容放在前面，或者是像sql中like zg% 这样的。

另外，我分词设置成如下

################################## Pinyin ###################################
index:
analysis:
analyzer:
pinyin_analyzer:
tokenizer: my_pinyin
filter: [standard,nGram]
tokenizer:
my_pinyin:
type: pinyin
first_letter: "prifix"
padding_char: " "

映射设置成如下：

POST /tag/keywords/_mapping
{
"keywords": {
"properties": {
"kwname": {
"type": "multi_field",
"fields": {
"kwname": {
"type": "string",
"store": "no",
"term_vector": "with_positions_offsets",
"analyzer": "pinyin_analyzer",
"boost": 10
},
"primitive": {
"type": "string",
"store": "yes",
"analyzer": "keyword"
}
}
}
}
}
}

http://localhost:9200/tag/_analyze?text=%E5%88%98%E5%BE%B7%E5%8D%8E&analyzer=pinyin_analyzer

结果是

{"tokens":[{"token":"l","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"ld","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"d","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"dh","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"h","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"hl","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"l","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"li","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"i","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"iu","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"u","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"ud","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"d","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"de","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"e","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"eh","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"h","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"hu","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"u","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"ua","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"a","start_offset":0,"end_offset":3,"type":"word","position":1}]}

这个有点太细了，怎么让他粗一些
比如就要
{"token":"liu","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"de","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"hua","start_offset":0,"end_offset":3,"type":"word","position":1},{"token":"ldh","start_offset":0,"end_offset":3,"type":"word","position":1},

应该怎么设置？

谢谢大神~~~~~

这样就变成

---

{"tokens":[{"token":"ldh liu de hua ","start_offset":0,"end_offset":3,"type":"word","position":1}]}

这样了，并不是每个pinyin都分开索引的~

[starckgates]

这个时候搜索不到内容了

{"took":1,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}

[medcl]

用prefix query试试，你的需求不就这个么？

额，好复杂，我试试，谢谢大神~

哦，对了大神，我看pinyin这里面创建索引用的settings，而不是在配置文件里设置的，这个是不是可以直接写在配置文件里来用？像ik分词那样，把analysis定义在.yml配置文件中？

[medcl]

standard filter你也去掉了么？

filter没去掉。
我写在.yml里了
如下

---

################################## Pinyin ###################################
index:
analysis:
analyzer:
pinyin_analyzer:
tokenizer: my_pinyin
filter: [standard]
tokenizer:
my_pinyin:
type: pinyin
first_letter: "prefix"
padding_char: " "

[medcl]

拼音analyzer的type没有设置为custom

这样吗？

[medcl]

是的,注意格式

[starckgates]

嗯，这里面好像一写代码就都靠右对齐了。。。
我试试

[starckgates]

可以了大神，谢谢大神。~~
