}分词器插件：
1，es搜索实现相关性的方式：
数据埋点
第一次搜索实现搜索词，数据埋点写入db.
第2次数据埋点对文档的类型，应用场景，目录分类进行数据埋点。
2 聚合查询（每查询一次先拿到聚合数据集合）
聚合查询数据把 文档的类型，应用场景，目录分类进行聚合成集合，根据
数据埋点的数据库数据获取到，进行优先排序到前面筛选（这里优先filter）
3，通过FunctionScoreQueryBuilder实现分数打分，也是根据数据埋点的数据进行设置boost进行boolQueryBuilder搜索
再次比如boost默认为30，如果我的热词有三条
那么就是 (30-i+1)/i+1 当前设置权重就是(10000-i+1)/i+1，热词的数据也是通过数据库分组查询统计。
总体实现思路：2次数据埋点+bool搜索在filter(优先按数据库的埋点过滤)+FunctionScore+filter+bool搜索实现搜索打分最后可以实现把用户经常看的文档能排到前面。
总结：
如果常规方式无法得到想要的评分结果，则可以脚本方式完全自己实现评分算法，以得到预期的评分结果。
function_score查询是用来控制评分的终极武器，它允许每个与主查询匹配的文档应用一个内置或自定义函数，已达到改变原始查询评分_score的目的。
script_score用于指定自定义脚本。params指定作为变量传递到脚本中的参数。
boost_mode字段用来指定新计算的分数与_score的结合方式，取值可以是：
multiply 相乘
? replace 替换
? sum 相加
? avg 取平均值
? max 取最大值
? min 取最小值
