How the Search Engine Works
Hi Everyone,
The term search engine is so common among researchers and developers in the information retrieval system. If you are new to this term, then you might be wondering what this term means. Basically this is a program that searches documents for specified keywords and gives a list of information on where the keywords are found. A search engine mainly uses a spider, an indexer and a proprietary algorithm. A spider works by fetching many documents from all fields and bringing them back to the search results. The indexer reads the documents and creates an index that matches with the words contained in each document.
The search engine consists of four units namely; the document processor, the query processor, search and matching function and the ranking capability. The duty of the document processor is to prepares, processes, and inputs the documents, pages, or sites that users search against. In the query processor the documents are checked to ensure that they match the query requirements. Having determined that the document meet the query requirement they are computed depending on the similarity of each document in the subset of documents. The ordering of the documents depends on the kind of system being used.
These are the main processes that occur, along with the many options that a search engine provider decides on. The variety of options may help elucidate users' frequent surprise at the results their queries return up till now. Search engine providers have mainly decide on less, against more, intricate processing of documents and queries. The representative search results leaves a lot of work to be done by the searcher, who must find their way through the results, clicking on and exploring a number of documents before finding exactly what they seek. The evolution of products and services suggests that this status will not continue. Some go further in the complexity and quality of the processing performed will be rewarded with greater adherence by searchers, as well as financially rewarding opportunities to serve as the search engine on more organizations or intranets.
Most search engines use these procedures to help in the ranking of pages. All these procedures involves the use of software and tools to make the processes a success. If you are planning on choosing a ranking system look for one that offers you the best results. Today there are many types available and most people find it hard to choose the best. A good one should be able to meet your requirements. When searching for a word in the search engine, it is possible for you not to note the processes of web crawling, building the index and building the search because the process is so fast.
