It is important to note that in many data structures or algorithmic books there will be a description of the jump table, the principle is roughly the same, but the definition of a slightly different: Definition of interval (Interval): Some think that the interval is 2, that is, the number of elements between the two upper elements, excluding two upper elements, or 3, that is, the difference between the two upper el

The test latency is caused by the change of the data set in the background banding and the new interface, it's not about lucene's efficiency) ItemTemplate: You can understand it when using WPF.
