Search engines are designed to find the right information based on keywords, relevance and quality. They are used for a wide range of purposes from making money to personalizing results based on user intent, location and past searches.

The goal is to get the best and most relevant results, so that users can trust that the content they see on a search engine result page (SERP) is accurate and will answer their query. Search engine technology continues to evolve to improve the accuracy, relevancy and quality of results. Newer technologies such as artificial intelligence are allowing for even more nuanced and personalized answers to complex queries.

Most people think of a search engine as a tool to find specific documents, images or websites that contain specific information. However, there are a number of other useful search techniques that can make the process much easier and quicker.

These search engine techniques are often called SEO or Search Engine Optimization and can be incorporated into the design of a website to maximize its visibility on a SERP. The primary goal of these techniques is to attract traffic to a website that can convert into customers, clients or an audience that keeps returning for more information.

There are three phases of a search engine – crawling, indexing and searching. The crawling phase is where the spiders go to each Web page to collect and record the textual contents. Then the pages are sorted and tagged to include or exclude information based on their importance. Once this is done the pages are stored in an index. When a search is entered, the engine searches its index for the relevant pages and displays them on its SERP in order of relevance.

Different search engines will produce different results for the same search query. This is because different search engines have their own indices and algorithms to sort the pages and rank them in a particular order for each search. The different algorithms also weigh different variables to determine the relative importance of a Web page.

One of the most common search engine techniques is to use the boolean operators AND, OR and NOT to refine a search query. The AND operator requires that all the words in a search are present, the OR operator allows for the possibility of missing or similar words to be included and the NOT operator eliminates results containing specified keywords.

Some search engines have more advanced features such as proximity searches or concept-based searching. Google for example has a feature that is known as the ‘Near Me’ search where users can enter a query such as “coffee shops near me”. Other search engines such as Wolfram Alpha and Shodan are dedicated to a specific type of information such as science or maths topics.
