startoffset和endoffset异常

[alaifu]

8.12.2版本，使用示例脚本：
PUT /medcl/
{
"settings" : {
"analysis" : {
"analyzer" : {
"pinyin_analyzer" : {
"tokenizer" : "my_pinyin"
}
},
"tokenizer" : {
"my_pinyin" : {
"type" : "pinyin",
"keep_separate_first_letter" : false,
"keep_full_pinyin" : true,
"keep_original" : true,
"limit_first_letter_length" : 16,
"lowercase" : true,
"remove_duplicated_term" : true
}
}
}
}
}创建索引后，
使用GET /medcl/_analyze
{
"text": ["刘德华"],
"analyzer": "pinyin_analyzer"
}
检索脚本，检索后没有startoffset和endoffset信息：
{
"tokens": [
{
"token": "liu",
"start_offset": 0,
"end_offset": 0,
"type": "word",
"position": 0
},
{
"token": "刘德华",
"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
}
]
}
