//(1)多条件查询,使用boolQuery must和filter的区别，filter只筛选数据，must会对数据进行评分  
//此处对使用query还是filter做个简单总结，全文检索以及任何使用相关性评分的场景使用query检索,其他情况使用filter检索。过滤查询（filter）是对集合包含/排除的简单检查，这使得它们计算速度非常快,当至少有一个过滤查询是“稀疏”（仅有少量匹配的文档）时，可以利用各种优化，并且可以将缓存经常使用的filter过滤查询缓存在内存中以加快访问速度。  
//对比之下，query检索(评分查询)不仅要查找匹配的文档，还要计算每个文档的相关程度，这通常会使其比非评分文档更复杂。 另外，查询结果不可缓存。
