Regarding the major functions of search engines, gordon and pathak (1999) stated that they provided three chief facilities: (1) they gathered together a set of web pages that form the universe from which a searcher could retrieve information; (2) they represented the pages in this universe in a fashion that attempted to capture their content; (3) they allowed searchers to issue queries; and (4) they employed information retrieval algorithms that attempted to find for them the most relevant.

Two main approaches are matching words in the query against the database index (keyword searching) and traversing the database using hypertext or hypermedia links. Keyword searching has been the dominant approach to text retrieval since the early 1960s; hypertext has so far been confined largely to personal or corporate information-retrieval applications.

Search engines represent a web-specific example of the information retrieval paradigm. The problem of web search has many additional challenges, such as the collection of web resources, the organization of these resources, and the use of hyperlinks to aid the search. Whereas traditional information retrieval only uses the content of documents to retrieve results of queries, the web requires stronger mechanisms for quality control because of its open nature.
The basic types of search engines include: web crawlers, meta, directories and hybrids. Within these basic types, there are many different methods used to the basic types of search engines include: web crawlers, meta, directories and hybrid.

Information retrieval is the process through which a computer system can respond to a user's query for text-based information on a specific topic. Ir was one of the first and remains one of the most important problems in the domain of natural language processing (nlp). Web search is the application of information retrieval techniques to the largest corpus of text anywhere — the web — and it is the context where many people interact with ir systems most frequently.
