问题及解决方法

must和should组合查询，should失效。使用must嵌套查询，将should组成的bool查询包含在其中一个must查询中。

SearchRequest request = new SearchRequest();
request.indices("function_log");

SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
if (StringUtils.hasText(schoolName)) {
    boolQueryBuilder.must(QueryBuilders.termQuery("schoolName.keyword", schoolName));
}
if (StringUtils.hasText(typeFunction)) {
    boolQueryBuilder.must(QueryBuilders.termQuery("typeFunction.keyword", typeFunction));
}
if (StringUtils.hasText(startTime) && StringUtils.hasText(endTime)) {
    boolQueryBuilder.must(QueryBuilders.rangeQuery("createDate").gte(startTime + "T00:00:00.000Z").lte(endTime + "T23:59:59.000Z"));
}
BoolQueryBuilder shouldQuery = QueryBuilders.boolQuery();
shouldQuery.should().add(QueryBuilders.termQuery("description.keyword","查询学生信息表"));
shouldQuery.should().add(QueryBuilders.termQuery("description.keyword","获取学校访客数据"));
boolQueryBuilder.must(shouldQuery);

sourceBuilder.query(boolQueryBuilder);
request.source(sourceBuilder);
System.out.println(sourceBuilder.toString());
