What are the two main parts of a search engine s work?

Think of a name that goes big.

Yours is so right.

2.Storage: The scraped content is stored in a temporary database.

3.Pre-processing: The stored content is processed and you can choose the content you like.

1.Crawling and crawling: first discover and collect web page information on the Internet;

2.Establishment of indexing database: Extracting and organizing information at the same time to establish an indexing database;

3.Ranking: The searcher then quickly checks out documents in the index database according to the query keywords entered by the user, evaluates the relevance of the document and the query, sorts the results to be output, and returns the query results to the user.

1. Web scraping.

Every time a spider encounters a new document, it searches for the page that links to its page. The process by which a search engine spider accesses a web page is similar to how a normal user accesses their page using a browser, i.e., BS mode. The engine spider first makes an access request to the page, and the server accepts the access request and returns the html**, and then stores the obtained html** in the original page database.

2. Preprocessing and indexing.

In order to make it easier for users to quickly and easily find search results in a database of raw web pages above the trillion level, search engines must preprocess the original web pages crawled by Spider. The most important process of web page preprocessing is to create a full-text index of a web page, then begin to analyze the web page, and finally create an inverted file (also known as reverse indexing).

1. Searcher: The searcher, also known as the web spider, is an automatic program used by search engines to crawl and crawl web pages, crawling in various nodes of the Internet without stopping in the background of the system, and discovering and crawling web pages as quickly as possible in the crawling process.

4. User interface: It provides users with a visual interface for query input and result output.

An Internet search engine is a complex software system designed to search large amounts of data on the World Wide Web. They help us (their users) understand what we need to know by providing the most relevant lists of specific words or phrases that we searched for. For most of us, search engines are the basic web tool.

Without them, we will have to remember the exact URL of each ** or page that we want to visit. While this may seem incredible to most people, there was actually a time when the internet worked like this. Fortunately, things have changed.
