Bool Query 用于组合多个叶子或复合查询子句的默认查询
must 相当于 与 & =
must not 相当于 非 ~ !=
should 相当于 或 | or
filter 过滤
boolQuery() .must(termQuery("content", "test1"))
.must(termQuery("content", "test4"))
.mustNot(termQuery("content", "test2"))
.should(termQuery("content", "test3"))
.filter(termQuery("content", "test5"));
