ES-analyzer

ik_dynamic_update和synonym_dynamic_update支持通过Mysql进行动态配置，使用前需要在配置文件中进行DB连接配置

ik_dynamic_update

支持通过MySQL配置IK扩展词、停用词热更新

synonym_dynamic_update

支持通过MySQL配置SYNONYM同义词热更新

# 是否打开数据库同义词库(true/false)
enable.synonym=true
url=
user=
password=

# 用户可以在这里配置MySQL同义词表名
synonym.table=dynamic_synonym_rule
# 用户可以在这里配置MySQL同义词表字段名称
synonym.field.name=word

# DB自定义词库同步内存刷新时间（单位秒）
refresh.time.interval=1800

pinyin-multiple

支持多音词全拼音的解析，内部涉及nlp-lang jar包依赖，故需要先部署新版的nlp-lang，再部署pinyin-multiple
