	Search engine ranking
		The aim of a search engines is to serve the user as well as possible.
		Search engine optimisation has become a very complex, sophisticated practice that requires constant research, practice, and re-evaluation to be effective.
		Search engine placement is the first, most valuable, and most cost-effective item in a marketing budget.

	Search algorithm - Wikipedia, the free encyclopedia
		In computer science, a search algorithm, broadly speaking, is an algorithm that takes a problem as input and returns a solution to the problem, usually after evaluating a number of possible solutions.
		Brute-force search or "naïve"/uninformed search algorithms use the simplest, most intuitive method of searching through the search space, whereas informed search algorithms use heuristics to apply knowledge about the structure of the search space to try to reduce the amount of time spent searching.
		Tree search algorithms are the heart of searching techniques.

	PlanetMath: binary search
		The binary search technique is a fundamental method for locating an element of a particular value within a sequence of sorted elements (see Sorting Problem).
		If, however, the value we are searching for comes before the middle element, then we repeat the search on the first half of the sequence.
		This is version 11 of binary search, born on 2001-10-07, modified 2004-03-25.

		During the number or figure code search, the line coincidence search is possible.
		Pattern or wildcard search (using the symbols “” and “?”) also apply, with the “” symbol resulting in any subline being recognised (including blank ones) and the “?” symbol applying similarly to single letters or figures.
		The search stops in two cases: if after the next search the sample list exceeds 10 articles or if the words that are impossible to exclude are absent.

	ongoing · On the Goodness of Binary Search
		On the other hand, binary search is so simple and robust that you can code up five subtly different binary searches for different places in your code, all using optimized direct references into your internal structures, and not suffer any software engineering angst.
		All that said, the core idea of binary search is mind-bogglingly simple; you have a sorted array, you look at the middle element which tells you what you're looking for is in the top or bottom half, then you take that half, rinse and repeat until done.
		Suppose, for example, you want to search for a range in that array; take two input numbers and find the index of the entry that is smaller than the lesser of them, and of the entry that is larger than the greater.

	A* search algorithm - Wikipedia, the free encyclopedia
		In computer science, A* (pronounced "A star") is a graph search algorithm that finds a path from a given initial node to a given goal node (or one passing a given goal test).
		In their paper, it was called algorithm A; using this algorithm with an appropriate heuristic yields optimal behavior, hence A*.
		Dijkstra's algorithm is a special case of A* where the heuristic is a constant function such as h(x) = 0 for all x.

	How Search Engines Rank Web Pages
		Search engines will also check to see if the search keywords appear near the top of a web page, such as in the headline or in the first few paragraphs of text.
		Search engines may also penalize pages or exclude them from the index, if they detect search engine "spamming." An example is when a word is repeated hundreds of times on a page, to increase the frequency and propel the page higher in the listings.
		In short, this means that a search engine may watch what results someone selects for a particular search, then eventually drop high-ranking pages that aren't attracting clicks, while promoting lower-ranking pages that do pull in visitors.

	AI Horizon: Binary Search Algorithm for Searching Sorted Arrays
		There are a variety of algorithms to search a sorted array, but we shall examine only two of them.
		That is, this algorithm has the order-of-magnitude similar to the logarithm of n to the base 2, where n is the number of elements in the sorted array.
		In each loop, the algorithm should check for three cases and act accordingly: if the target is equal to the middle element, if the target is less than the middle element, or if the target is greater.

	Hello World - Intelligent Search Algorithms
		Heuristic algorithms are more efficient because they take advantage of feedback from the data to direct the search path, while brute-force algorithms follow the same path regardless of the data being tested.
		This algorithm is one of the most efficient search algorithms, and therefore, it is used in AI application when a complex search need to be done, as in planning applications.
		A combination of two or more search algorithms is used to benefit from the advantages of each of them and minimize the effect of the disadvantages.

	The Shark-Search Algorithm
		Figure 1 is a description of the fish-search algorithm (in a simplified form, omitting some optimization details for the sake of the generality).
		In contrast, by integrating search heuristics such as the fish- or shark-search algorithms in the crawling process so as to go more deeply in directions where relevant information was found, we allow users to generate maps tailored to their interests.
		We implemented both the fish- and the shark-search algorithms in a dynamic tailorable site mapping tool, Mapuccino, and experimentally verified that significant improvements were achieved in terms of the total of relevant information discovered in the same small amount of time.

	Binary search algorithm - Wikipedia, the free encyclopedia
		A binary search algorithm (or binary chop) is a technique for finding a particular value in a linear array, by ruling out half of the data at each step, widely but not exclusively used in computer science.
		A binary search is an example of a divide and conquer algorithm (more specifically a decrease and conquer algorithm) and a dichotomic search (more at Search algorithm).
		The search begins by examining the value in the center of the list; because the values are sorted, it then knows whether the value occurs before or after the center value, and searches through the correct half in the same way.

	MITID Search Algorithm
		The search algorithm follows a multiple step process to identify records that either match or possibly match given search criteria.
		The first step of the search algorithm is to identify all of the potential matches by using selection criteria that will retrieve a generous subset of the records from the ID database.
		If either the search criteria field or the corresponding target record field is empty, the field is flagged as missing data.

		State space search, then, is solving a problem by beginning with the start state, and then for each node we expand all the nodes beneath it in the graph by applying all the possible moves that can be made at each point.
		When the algorithm begins the start state is placed on the open list, it is the only state we know about and we have not expanded it.
		Any graph search algorithm is said to be admissible if it always returns an optimal soution, that is the one with the lowest cost, if a solution exists at all.

		In other words, for the criteria to be met, the condition must be satisfied in whole within the context of a single data attribute.
		For example: In the existing algorithm, if the word fragment 'CAT' appeared anywhere in the description, and the number '5' appeared in the model, then a search for 'CAT 5' would be satisfied..
		What is intended is that the fragment 'CAT' and/or the number '5' both appear in the Description or both appear in the model (etc) for the condition to be satisfied.

		This search reduces to a well-known graph search problem, namely the problem of finding the shortest path in a directed acyclic graph with uniform weights.
		The first step of the algorithm is a topological sort of the vertices of the graph.
		It turns out that the state names of the word-graph that we obtain from the speech recogniser are already topologically sorted: state names are integers, and edges always connect to larger integers.

		Although search engine algorithms are closely guarded secrets,there are general guidelines that if closely adhered to will increase your web site's position in the results delivered to searchers.
		This means that a search engine may watch which results someone clicks on for a particular search, dropping high-ranking pages that aren't attracting clicks, while promoting lower-ranking pages that do attract clicks.
