缺少 “wangkai“ 和 “wk”

{
    "tokens": [
        {
            "token": "w",
            "start_offset": 0,
            "end_offset": 1,
            "type": "CN_CHAR",
            "position": 0
        },
        {
            "token": "wang",
            "start_offset": 0,
            "end_offset": 1,
            "type": "CN_CHAR",
            "position": 0
        },
        {
            "token": "王",
            "start_offset": 0,
            "end_offset": 1,
            "type": "CN_CHAR",
            "position": 0
        },
        {
            "token": "k",
            "start_offset": 1,
            "end_offset": 2,
            "type": "CN_CHAR",
            "position": 1
        },
        {
            "token": "kai",
            "start_offset": 1,
            "end_offset": 2,
            "type": "CN_CHAR",
            "position": 1
        },
        {
            "token": "楷",
            "start_offset": 1,
            "end_offset": 2,
            "type": "CN_CHAR",
            "position": 1
        }
    ]
}
