Search Engine Techniques

Search engines are a fundamental technology that allows users to quickly locate information on the Internet. A search engine carries out systematic searches on the World Wide Web, a collection of websites, and returns the results of those searches in a list often referred to as Search Engine Result Pages (SERPs). Search engines are widely used by businesses looking for potential customers, academics looking for research or data, and people who need to find specific documents like a legal contract or medical records.

Although every database and search engine is different, there are some common techniques that can be applied to any search. Using these methods can help you get better and more relevant search results.

The first step in a search is identifying what keywords you need to target in your query. This is done by analyzing the words that appear on your page and using them as a basis for the search. Keywords can be single words, short phrases or abbreviations.

Once the search terms have been identified, the search engine will gather the information from the web and index it in a repository called an index. It then uses its algorithm to sort the information and rank the results based on a given query.

It is important to keep in mind that the ranking of a search engine result page can be influenced by many factors. These can include website and page popularity, the number of incoming links to a site or webpage, how authoritative and trusted the source is and even social media activity. A whole science has developed in the last few decades to manipulate these variables and ensure that a webpage is at the top of search engine results, a process known as Search Engine Optimization (SEO).

Another important technique is to use boolean operators such as OR or AND to broaden your searches. For example, searching for children OR kids will return any document that contains both words. This is particularly useful if you are looking for synonyms or related information.

Truncation and wildcards are also common search engine techniques. Truncation involves searching for the root word with a wildcard symbol, typically an asterisk (*) or question mark (?). This allows the database to search for all words that start with the same letters, regardless of their endings or spelling. Wildcards can also be used to replace letters or parts of a word.

It is also worth noting that although a search engine is programmed to produce the best results for a given query, empirical studies suggest that there are various political, economic and social biases in the information provided by search engines. These can be a result of commercial and advertising processes (e.g., promoting certain websites or companies that pay to advertise with the search engine), social and economic processes (e.g., discrimination or censorship), or simply a result of the inherent limitations and assumptions of the underlying technology.
