二 问题与解决
1 multiMatchQuery 查询与 kibana中不一致
这是由于minimumShouldMatch参数导致，easy-es默认为60，设置为50解决。
//按照得分排序wrapper.multiMatchQuery(req, Operator.OR,50,BoSopContentES::getSop_title, BoSopContentES::getSop_content).sortByScore();List<BoSopContentES> list1=sopMapper.selectList(wrapper);2 org.dromara.easyes.common.exception.EasyEsException: no such method
es 实体创建id，es数据中无需修改
/*** ES的id(必须)*/@IndexId(type= IdType.CUSTOMIZE)private String id;
