According to the imitation of search technology, the search engine only has three kinds of directory search, full-text search engine and meta search engine, but there are many vertical search engines extended and derived from these three search engine applications, it can be said that according to the classification of national economic industries, almost every industry has its own vertical search engine, such as: real estate search, tourism search, commercial Sui Dasheng search, etc., countless.

In the section on the classification of search engines, we mentioned the concept of full-text search engines extracting information from ** to establish a web page database. There are two types of automatic information gathering in search engines. One is regular search, that is, every once in a while (for example, Google is generally 28 days), the search engine takes the initiative to send out a "spider" program to retrieve the Internet within a certain IP address range, and once a new one is found, it will automatically extract the information and add it to its own database.

The other is to submit a search, that is, the owner actively submits to the search engine, which sends a "spider" program to you within a certain period of time (ranging from 2 days to several months) to scan your search and store the relevant information in the database for user query. Since the search engine indexing rules have changed a lot in recent years, actively submitting ** does not guarantee that your** can enter the search engine database, so the best way at present is to get more external links, so that search engines have more chances to find you and automatically include you**.

When the user searches for information with keywords, the search engine will search in the database, and if it finds the content that matches the user's requirements, it will use a special algorithm - usually according to the degree of matching of keywords in the web page, the frequency of the position, the quality of the link, etc. - to calculate the relevance and ranking level of each web page, and then return these web links to the user in order according to the degree of relevance.

This problem is really complicated, and it is difficult for anyone to give you satisfaction.

In fact, search engines involve theories and technologies in many fields: digital libraries, databases, information retrieval, information extraction, artificial intelligence, machine learning, natural language processing, computer linguistics, statistical data analysis, data mining, computer networks, distributed processing, etc., which are comprehensive and challenging.
