Specific applications of search algorithms include: Problems in combinatorial optimization, such as: . The vehicle routing problem, a form of shortest path problem; The knapsack problem: Given a set of items, each with a weight and a value, determine the number of each item to include in a collection so that the total weight is less than or equal to a given limit and the total value is as ...
The concept of a search domain plays an important part in all this. By default it is just article space, but in general a search domain starts out as a set of namespaces, and ends up as all the pages in the search result. One term of a query will set the search domain for another term in the same query. The order is optimized by the search engine.
A search engine maintains the following processes in near real time: [34] Web crawling; Indexing; Searching [35] Web search engines get their information by web crawling from site to site. The "spider" checks for the standard filename robots.txt, addressed to it. The robots.txt file contains directives for search spiders, telling it which pages ...
A search engine operates by performing specific functions When seeking online information, many people turn to search engines like Google, Bing, Yahoo, or AOL Search. These search engines function as digital indexes, organizing available content by topic and sub-topic, much like an index in a book.
Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval.Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science.
Ranking of query is one of the fundamental problems in information retrieval (IR), [1] the scientific/engineering discipline behind search engines. [2] Given a query q and a collection D of documents that match the query, the problem is to rank, that is, sort, the documents in D according to some criterion so that the "best" results appear early in the result list displayed to the user.

Other types of search engines do not store an index. Crawler, or spider type search engines (a.k.a. real-time search engines) may collect and assess items at the time of the search query, dynamically considering additional items based on the contents of a starting item (known as a seed, or seed URL in the case of an Internet crawler).
