Search algorithms of Search Engines

There are many parts of a Search Engine. All are very important and have their own performance. But the search algorithm is the only part that makes everything to work well. We can say that the search algorithm is the foundation on which everything else is built. Working principal totally depends on the search algorithms of a search engine. So before going to deep in working methods we should first see this part.

Search Engine Algorithms, Algorithm for Search Engine, Search Engine Optimization Algorithm, Google Search Algorithm, List Search Algorithm, Informed Search Algorithm, Constraint Satisfaction Search Algorithm, SQL Search Algorithm

Basically Search Algorithm is problem solving techniques and procedures that take problems, evaluate them and tell a number of different solutions and answers. And then most accurate solution is adopted. The point to note here is that how it takes problems and how it performs its actions. A search algorithm for a search engine takes the problem (the word or phrase being searched for), sifts through a database that contains cataloged keywords and the URLs those words are related to, and then returns pages that contain the word or phrase that was searched for, either in the body of the page or in a URL that points to the page.

This neat little trick is accomplished differently according to the algorithm that’s being used. There are several classifications of search algorithms, and each search engine uses algorithms that are slightly different. That’s why a search for one word or phrase will yield different results from different search engines.

Some of the most common types of search algorithms include the following:

Search Engine Algorithms, Algorithm for Search Engine, Search Engine Optimization Algorithm, Google Search Algorithm, List Search Algorithm, Informed Search Algorithm, Constraint Satisfaction Search Algorithm, SQL Search Algorithm

·        List search:

In List Search Algorithm, data is searched through specified data looking for a single key. In this method data is searched in very linear and list style method. The result of a list search is usually a single element, which means that searching through billions of web sites could be very time-consuming, but would yield a smaller search result.

·        Tree search

Envision a tree in your mind. Now, examine that tree either from the roots out

Or from the leaves in. This is how a tree search algorithm works. The algorithm searches a data set from the broadest to the narrowest or from the narrowest to the broadest.

Data sets are like trees; a single piece of data can branch too many other pieces of data, and this is very much how the Web is set up. Tree searches, then, are more useful when conducting searches on the Web, although they are not the only searches that can be successful.

·        SQL search

One of the difficulties with a tree search is that it’s conducted in a hierarchical manner, meaning it’s conducted from one point to another, according to the ranking of the data being searched. A SQL (pronounced See-Quel) search allows data to be searched in a non-hierarchical manner, which means that data can be searched from any subset of data.

·        Adversarial search

An adversarial search algorithm looks for all possible solutions to a problem, much like finding all the possible solutions in a game. This algorithm is difficult to use with web searches, because the number of possible solutions to a word or phrase search is nearly infinite on the Web.

·        Informed search

An informed search algorithm looks for a specific answer to a specific problem in a tree-like data set. The informed search, despite its name, is not always the best choice for web searches because of the general nature of the answers being sought. Instead, informed search is better used for specific queries in specific data sets.

·        Constraint satisfaction search

When you think of searching the Web for a word or phrase, the constraint satisfaction search algorithm is most likely to satisfy your desire to find something. In this type of search algorithm, the solution is discovered by meeting a set of constraints, and the data set can be searched in a variety of different ways that do not have to be linear. Constraint satisfaction searches can be very useful for searching the Web.

These are only a few of the various types of search algorithms that are used when creating search engines. And very often, more than one type of search algorithm is used, or as happens in most cases, some proprietary search algorithm is created. The key to maximizing your search engine results is to understand a little about how each search engine you’re targeting works. Only when you understand this can you know how to maximize your exposure to meet the search requirements for that search engine.
