在更新率和覆盖率等关键性能上当前的搜索引擎多年来几乎没有任何明显的改进。
This condition hasn't changed for many years. Converge and recency problems have become the bottleneck problem of current web search engine.
改进算法使搜索引擎的排序结果更符合查询条件，相应的查确率也有很大提高。
The improved algorithm can make the search engine ranking results more in line with the query, and the corresponding precision rate has also been greatly improved.
改进算法不仅能减少搜索的盲目性，提高命中率，而且可以用于估算网格工作流执行时间。
It can not only reduce the searching blindness and improve success rate of search, but also can be used to estimate the execution time of a Grid workflow.
