<information science> A search based on frequencies of the search terms in the documents being searched. Weighted search is often used by search engines. It produces a numerical score for each possible document. A document's score depends on the frequency of each search term in that document compared with the overall frequency of that term in the entire corpus of documents. A common approach is called tf.idf which stands for term frequency * inverse document frequency. Term frequency means "the more often a term occurs in a document, the more important it is in describing that document." http://ciir.cs.umass.edu/cmpsci646/ir4/tsld034.htm Inverse document frequency means the more documents a term appears in, the less important the term is. A simple weighted search is just a list of search terms, for example: car automobile Weighted search is often contrasted with boolean search. It is possible to have a search that syntactically is a boolean search but which also does a weighted search. See also query expansion.

In finance, the weighted-average life (WAL) of an amortizing loan or amortizing bond, also called average life,PIMCO glossaryBloomberg Glossary is the weighted average of the times of the principal repayments: it's the average time until a dollar of principal is repaid.

In applied mathematics, methods of mean weighted residuals (MWR) are methods for solving differential equations. The solutions of these differential equations are assumed to be well approximated by a finite sum of test functions \phi_i.

The Weighted Companion Cube (also simply called the Companion Cube) is a fictional item featured in the Portal series of video games by Valve Corporation. Initially featured in a single level of the original Portal, Test Chamber 17, as one of Aperture Science's ubiquitous Weighted Storage Cubes with heart symbols printed on the outside, it is given to the game's main character, Chell, as part of the antagonist GLaDOS's sinister testing initiative.

Search analytics is the use of search data to investigate particular interactions among Web searchers, the search engine, or the content during searching episodes.Jansen, B.

A ternary search algorithm is a technique in computer science for finding the minimum or maximum of a unimodal function. A ternary search determines either that the minimum or maximum cannot be in the first third of the domain or that it cannot be in the last third of the domain, then repeats on the remaining two thirds.

In computer science, an exponential search (also called doubling search or galloping search or Struzik search) is an algorithm, created by Jon Bentley and Andrew Chi-Chih Yao in 1976, for searching sorted, unbounded/infinite lists. There are numerous ways to implement this with the most common being to determine a range that the search key resides in and performing a binary search within that range.

A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query.
