How a Search Engine

How a Search Engine - After yesterday I was talking about how the spiders in search engines, here are a continuation of the contents of a blog post yesterday. This time I will talk about indexing and pencaraian.Setelah spider web or gather information from blogs and search engines then store them in an index database for later query. The main purpose of indexing is to find the information as quickly as possible. The search engine can only store the keywords and URL of a page in their database.

How a Search Engine - To create an efficient and useful results, then save the search engine keywords and URLs. Usually the search engines keep a number of key words that will appear on the page. The machine can give ratings to each web page / blog, depending on many factors like backlinks, keyword, relevance of content.

How a Search Engine - But every search engine uses different algorithms on how the indexing of pages. So this is one reason why different search engines produce different search list for a particular keyword search.

Spider "takes Web content pages / blog and create a password that allows online users to find the page they are looking for.

When users search for certain keywords in search engine, the engine returns a list of web pages that best match the database to check the index. Then give a brief description of content that contains the titles and URLs in the SERPs. To use search engines more efficient you can follow the instructions below:

- AND - All keywords with "AND" would be much better in a web page or document. We can change     "AND" with "+" in some search engines.

- OR - We can change "OR" with "|" in some search engines.

- Quotation Marks - The word between quotation marks is considered as a phrase. Would that have to be on a web page.
