), which ensures that some documents are returned first. Repeated use of keywords will widen the full-text indexing of these specific keywords and allow MSSearch to waste time finding the correct rows and counting the rows. If you have a large number of full-text indexing data and try to use this method, you may find that some full-text queries are time-consuming. If you can achieve a more granular (and possibly more accurate) "Best choice" system, yo

different types of optical fiber to assume the responsibility of transmission. Dispersion compensated fiber (DCF) The optical fiber dispersion can widen the pulse and cause the error rate. This is a problem that must be avoided in communication network, and also a subject to be solved in long-distance transmission system. Generally speaking, the dispersion of optical fiber consists of material dispersion and waveguide structure dispersion, material

For a weighted graph, the value obtained by adding the weights of the edges of all vertices at different parts is defined as the cut capacit

The InnoDB provides a row lock (locking on row level) that provides an unlocked read (non-locking read in selects) that is consistent with the Oracle type. These features improve the performance of multi-user concurrency operations. There is no need to widen the lock (lock escalation) in the InnoDB table because
