Hi @medcl

最近在打算使用 Phrase Suggester 的时候碰到点困难，想咨询下是不是哪里出了问题。

比方说我的 Mapping 是这样设置的：

"title_zh": {"type": "text", "analyzer": "ik_max_word", "search_analyzer": "ik_max_word"} "title_en": {"type": "text"}

title_zh和title_en分别是document中两个field，title_zh采用IK分词，title_en采用默认的分词。

随后我随便塞一个document进去，其中两个字段内容分别是： "title_zh": "苹果手机", "title_en":"apple iphone"

接下来我想使用 Phrase suggester 的功能：

curl -XPOST 'localhost:9200/anew/_search?pretty' -H 'Content-Type: application/json' -d' { "suggest": { "text": "applo iphene", "simple_phrase": { "phrase": { "field": "title_en", "size": 1, "gram_size": 3, "highlight": { "pre_tag": "", "post_tag": "" } } } } } '

返回结果是我想要的： { "took" : 2, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 0, "max_score" : 0.0, "hits" : [ ] }, "suggest" : { "simple_phrase" : [ { "text" : "applo iphene", "offset" : 0, "length" : 12, "options" : [ { "text" : "applo iphone", "highlighted" : "applo iphone", "score" : 0.24598429 } ] } ] } }

但是换做title_zh这个field却不行，是哪里配置不对呢？ curl -XPOST 'localhost:9200/anew/_search?pretty' -H 'Content-Type: application/json' -d' { "suggest": { "text": "平果手机", "simple_phrase": { "phrase": { "field": "title_zh", "size": 1, "gram_size": 3, "highlight": { "pre_tag": "", "post_tag": "" } } } } } '

{ "took" : 1, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 0, "max_score" : 0.0, "hits" : [ ] }, "suggest" : { "simple_phrase" : [ { "text" : "平果手机", "offset" : 0, "length" : 4, "options" : [ ] } ] } }
