History of Search Technology,

Search engine technology,

A search engine is a software program for finding information, crawling, modifying, and storing retrieval and presentation information in response to user queries. 

The search engine usually contains four items e.g. search interface, crawl (also known as spider or bot), indexer, and database. The searcher cuts through the collection of documents resume the text of the text and provide the surrogates for storage in the search engine index. Online search engines store images, link data, and document metadata as well.

The concept of hypertext and memory extension comes from an article published in The Atlantic Monthly in July 1945 by Vannevar Bush, entitled As We May Think. Within the article, Vanesvar urged scientists to work together to help build knowledge of the entire human body. He then proposed a system for storing unlimited, fast, reliable, and expandable memory storage systems. He named the device memex.

Bush views the concept of “indexing associative indexing” as his main contribution to the concept. As he explained, this was “a condition in which every object was created with a tendency to choose another and automatically. This is an important feature of the memex. The process of putting two things together is important. This “link” (as we have now said) creates a “trace” of paper that can be named, coded, and retrieved. Moreover, after the first two things were put together, “many things” could not “be combined into a channel”; “They can be revised in sequence, sooner or later, by diverting the oar like the one used to turn the pages of a book. It is as if material things were being collected from a different source and had been put together into a new book ”

All documents used in the memex will be in the form of a microfilm copy obtained as such or, in the case of your records, converted into microfilm by the machine itself. Memex will also use new recovery techniques based on a new type of integration of basic concepts in the basic concept where anything can be triggered by a quick and automatic choice to create personal “tracks” with linked texts. The new processes Bush expected to maintain data retention and retrieval will lead to the creation of completely new types of encyclopedias.

The most important machine, conceived by Bush and considered to be close to modern hypertext systems, is the assembly line. It can be a way to create new line sequences of microfilm frames across any inconsistent sequence of microfilm frames by creating chain-bound sequences of links in an aforementioned way, as well as personal comments and sidebars. An important feature of the memex is the process of combining two things together … When a user builds a route, calls it in his codebook, and then downloads it to his keyboard. In front of him are two objects that must be covered, displayed in nearby viewing areas. At the bottom of each one, there are many blank spaces, and a cursor is used to indicate one of these for each item. The user is typing one key, and the items are permanently merged … After that, any time, when one of these items is detected, the other can be immediately remembered by tapping the button below the corresponding code area.

Bush does not define any automatic search, any general metadata system such as standard library partitions or hypertext elements. Instead, when a user made an entry, such as a new or defined manuscript, or an image, he was expected to identify and explain it in his codebook. Later, by checking his codebook, the user can retrieve unspecified and performed entries.

In 1965 Bush participated in MIT’s INTEX project, to develop machine technology to process library information processing. In his 1967 speech entitled “Memex Revisited”, he pointed out that the invention of the digital computer, transistor, video, and other similar devices made the operation of the machine possible, but the cost would delay its success. He was right too.

Ted Nelson, who later did pioneer work with the first hypertext program and coined the term “hypertext” in the 1960s, called Bush his greatest influence.
