When the search engine in the internet after the birth of technology has been flying at the speed of the general progress. Even if the search engine service provider has the technology, manpower, the financial guarantee, the search engine still needs to face many technical challenges. Now the quality of search results has reached the user's needs. But this is only the beginning, the search engine will have more innovation, to provide more accurate content.

First, the search engine on the page to crawl faster and more comprehensive

Countless pages are updated, created, and countless users publish information on the Internet every day. To return to the most useful content search engines will crawl the most useful pages. Because of the huge page data, it takes a long time to update the spider. Mainstream search engines (such as Google, Baidu) have been able to update important pages in a few days. High-weight site information on a few hours or even a few minutes can be included, but some new stations do not have the weight of the site many pages are not valued for several months is also very normal.

Search engine to return the best content, in the crawl page must be comprehensive. This requires solving a lot of technical problems.

II. Massive data storage

Large Web sites are just hundreds of thousands of pages, and you can think about the amount of data on all the Web sites on the Internet. Search engines not only crawl pages, but also store effective data.

In addition to page data, search engines also need to store a direct link between the page and a large number of historical data, such data volume is unimaginable to users, such large-scale data storage and access must be a great technical challenge.

Third, the query processing needs to be fast and accurate

Users are the only way to see the search engine when they use search engines. When the user clicks "Search", the result is seen in less than a minute. Seemingly simple process, actually designed to very complex background processing. How do you quickly form from thousands of pages to the most reasonable, relevant, authoritative arrangement in less than a second?

Search engine needs to judge the user intention and artificial intelligence

It is still at an early stage to judge the user's intention. The same keywords, different users may be looking for different results. such as: Search "TV", the user in the end is to understand the television, or TV? This time the search engine how to the relevant page rankings to meet the needs of users? It is impossible to judge the user's personal search habits.

Search engines are currently working on the understanding of user search habits and historical data to determine search intentions and return more relevant results. Search engine can reach the level of artificial intelligence, understand the user's intention and purpose, look forward to it!
