Google search to launch powerful algorithms: dry 5.5 billion search results-
Google optimization,
Google, search engine-IT information
This sentence actually says is the world's largest search engine Google. According to Search Engine Land reports, in the search service Google has in their vast, deep integration, a method named RankBrain. This algorithm has been used in every time a user searches.

It sounds nothing but RankBrain is Google new algorithm based on machine learning, artificial intelligence developed, specifically designed to optimize search engine page rank. At present, Google hundreds of factors used to determine page rank, importance of RankBrain has been ranked third.
Specific works on RankBrain, we can look at the following example:
Enter in the Google "best flower shop in Los Angeles," so that the less common search requests, RankBrian by semantic analysis and Word Association, finds it and search more frequently "best LA flower shops" are more like finally showing the latter's search results.

So, RankBrain to solve the problem is more complex, unfamiliar or ambiguous statement that search. You know, users enter a search term on Google, 15% is never seen, about 825 million entries. Through RankBrian,Google you can get this part analyzes entry and back matching, making search results more accurate.
Of course, RankBrain does not affect the page rank for all search results. But behind the seemingly calm, placid, search box, Google has the technology behind it were numerous adjustments and optimization.

Googe gradually introduced the RankBrain in early 2015, just put it on the part of the search results. This algorithm began as the 55duoyici search service every day.
Report: Web site Search Engine Land search engine research a set of estimates on the number of Google search terms:
Year: 2 trillion;
Per month: 167 billion;
Daily: 5.5 billion;
Time: 228 million;
Every minute: 3.8 million;
Per second: 63,000.
谷歌搜索推出强悍算法：不动声色优化55亿搜索结果 -

这句话其实说的是全世界最大的搜索引擎Google。据 Search Engine Land报道，Google已经在自家庞大的搜索服务中，深度集成了一种名为 RankBrain 的算法。目前这项算法已经被运用在用户的每一次搜索中。

虽然听起来没什么，但RankBrain却是Google基于机器学习人工智能技术开发出来的最新算法，专门用来优化搜索引擎的网页排名。目前，在Google用来决定网页排名的数百个因素中，RankBrain的重要性已经位居第三。
关于RankBrain的具体工作原理，我们可以看下面这个例子：
在Google中输入“best flower shop in Los Angeles”这样不太常见的搜索请求，RankBrian 会通过语义分析和词库联想，认定这句话与搜索频率更高的“best LA flower shops”比较像；最后展示出后者的搜索结果。

所以说，RankBrain要真正解决的问题是看起来比较复杂，陌生或者有歧义的语句搜索。要知道，用户在Google上输入的搜索词条中有15%是从来没有见过的，约为8.25亿个词条。而通过RankBrian，Google可以将让这部分词条进行分析和重新匹配，从而使得搜索结果更加准确。
当然，RankBrain并不会对所有搜索结果的网页排名造成影响。但是在看似不动声色、波澜不惊的搜索框背后，Google已经对其背后的技术进行了无数的调整和优化。

Googe于2015年初逐步推出了RankBrain，当时只是把它用在一部分搜索结果上。现在这个算法已经开始为每天的55多亿次搜索服务。
附：搜索引擎研究网站Search Engine Land的关于Google搜索词条数目的一组估算数据：
每年：2万亿条；
每月：1670亿条；
每天：55亿条；
每时：2.28亿条；
每分：380万条；
每秒：6.3万条。
