Cause of the problem:
There are too many splicing bool queries, there is an upper limit for splicing, and the default setting of es is 1024

Solution:

方案一：当超过1024时可以将一个bool查询拆成两个子bool查询，使用must关键字，使得两个子bool查询是与的关系
方案二：编辑elasticsearch.yml，添加如下配置
    index.query.bool.max_clause_count: 10240
    注意：必须在最前面添加一个空格，即和其他配置首字母对齐，不然es启动报错。
方案三：由于索引分词使用了同义词，可以将查询分词和索引分词分开，单独设置查询分词
