E是一个泛型，任何对象都可以的。比如一个集合定义了String类型，那么就是 add("a")类似这样子

boolean addAll(int index,Collection<? extends E> c)将指定 collection 中的所有元素都插入到列表中的指定位置（可选操作）。将当前处于该位置的元素（如果有的话）和所有后续元素向右移动（增加其索引）。新元素将按照它们通过指定 collection 的迭代器所返回的顺序出现在此列表中。如果在操作正在进行中...

What is the bug? This is a bug for three related issues around booleans in WHERE clauses. I suspect without proof that they all have a similar root cause. All examples here use the ecommerce dataset as an example index, but should be rep...
I’m presuming that as you add search terms they effectively create Boolean “OR” statements whereby results will match at least one of the terms. Historically, I’ve referred to this as conceptual search or Level 2 Talent Mining. While very effective, the challenge for most people is that...
