Any detail is virtually available in the internet provided we know where to look for it and the search engine is the tool that helps us to locate it. The search results are usually listed out to the user, who can select the result that is best suited for the query. In simple words, a search engine is only a software program that searches the internet for specific keywords that are inputted by the user and returns results.

Short History:

As the number of web servers present in the internet increased, no single organization could keep list of all the servers. A tool was first created in 1990 which was known as archive, as it stored the archived information of various web servers. Then in 1993, an MIT professor programmed a web robot, which was soon followed by a CMU backed website called Lycos which was the first search engine ever built. Slowly other companies started cropping up in the search engine business. Google which is highly popular was first introduced as a test project in the late 1990’s.

How do they work?

The algorithm that a search engine is based upon is very complex and not easy to program or understand, so here we give the important aspects based on which a search engine actually works.

  • Query input by the user

This involves the process of the user actually inputting the required query into the search engine. The search engine takes this input as a string and stores it in an array.

  • Sorting millions of pages within a database:

The local database that stores various keywords as representatives to websites is searched for using the stored array. Once the required results are fetched, they are displayed out to the user.

  • Showing the results based on ranking of the pages.

The user can now see the search results for the keyword that was inputted, and has the liberty to choose which ever result he deems fit.

The strategy used for storing of these websites in the database includes a process called as crawling. In this process, a web robot or a crawler is sent to various websites. This crawler looks for tags and keywords and the web site is stored in the index based on the specific keywords. The usefulness of a search engine usually is directly proportional to the accuracy of the result that is being displayed. If the search result and the search terms do not match, it means there is a flaw in the in the algorithm that is used for searching the database and the process was a failure.

The Future:

With ever increasing dependency on search engine, it has become evident that they will always remain an integral part of the internet. So search engine providers are constantly working on various techniques that will not only enhance their presence but also make their search engine one of the best available
