按照提问区的例子进行测试的，输入简拼的完全匹配的情况，高亮数据会重复，请问有解决方案吗？

DELETE medcl
PUT /medcl/
{
"index" : {
"analysis" : {
"analyzer" : {
"pinyin_analyzer" : {
"tokenizer" : "my_pinyin"
}
},
"tokenizer" : {
"my_pinyin" : {
"type" : "pinyin",
"keep_full_pinyin" : true,
"keep_original" : false,
"limit_first_letter_length" : 16,
"lowercase" : true,
"remove_duplicated_term":true,
"ignore_pinyin_offset": false,
"keep_first_letter":true,
"keep_separate_first_letter" :true
}
}
}
}
}
POST /medcl/doc/_mapping
{
"properties": {
"name":{
"type": "text",
"fields": {
"py": {
"type": "text",
"analyzer": "pinyin_analyzer",
"search_analyzer": "pinyin_analyzer"
},
"name":{
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
}
}

}

}
}

POST medcl/doc/1
{
"name":"小动物耳病"
}

POST medcl/_search?size=50
{
"query": {
"multi_match": {
"fields": ["name","name.py"],
"query": "xdweb"

}

},
"highlight": {
"fields": {
"name":{
},
"name.py":{}
}
}
}

结果如下：
