       - chinese是中文分词，适合被索引列主要是中文的情况，性能比english分词低
       - unicode是多语言混合类型分词，适用于中英文混合、多语言混合的情况。它能够对邮箱前缀和后缀、IP地址以及字符数字混合进行分词，并且可以对中文按字符分词。
     - parser_mode用于指定分词的模式，目前parser = chinese时支持如下几种模式：
-      - fine_grained：细粒度模式，倾向于分出比较短的词，比如 '武汉长江大桥' 会分成 '武汉', '武汉市', '市长', '长江', '长江大桥', '大桥' 6个词
-      - coarse_grained：粗粒度模式，倾向于分出比较长的词，，比如 '武汉长江大桥' 会分成 '武汉市' '长江大桥' 2个词
+      - fine_grained：细粒度模式，倾向于分出比较短的词，比如 '武汉市长江大桥' 会分成 '武汉', '武汉市', '市长', '长江', '长江大桥', '大桥' 6个词
+      - coarse_grained：粗粒度模式，倾向于分出比较长的词，，比如 '武汉市长江大桥' 会分成 '武汉市' '长江大桥' 2个词
       - 默认coarse_grained
     - support_phrase用于指定索引是否支持MATCH_PHRASE短语查询加速
       - true为支持，但是索引需要更多的存储空间
