求助，使用match_phrase搜索不到结果

查看分词结果
GET pinyin_test/_analyze
{
"field": "name.pinyin",
"text": ["刘德华"]
}

{
"tokens" : [
{
"token" : "liu",
"start_offset" : 0,
"end_offset" : 0,
"type" : "word",
"position" : 0
},
{
"token" : "ldh",
"start_offset" : 0,
"end_offset" : 0,
"type" : "word",
"position" : 0
},
{
"token" : "de",
"start_offset" : 0,
"end_offset" : 0,
"type" : "word",
"position" : 1
},
{
"token" : "hua",
"start_offset" : 0,
"end_offset" : 0,
"type" : "word",
"position" : 2
}
]
}
含有ldh，但是使用match_parse却搜索不到
GET medcl/_search
{
"query": {
"match_phrase": {
"name.pinyin": "ldh"
}
}
}

{
"took" : 0,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 0,
"relation" : "eq"
},
"max_score" : null,
"hits" : [ ]
}
}

用 POST medcl/_search
{
"query": {
"match_phrase": {
"name.pinyin": "liudehua"
}
}
}
必须每个 position 都有和 刘德华 分词结果匹配的token

ldh 分词后 相同 position 会有不匹配的token
