	Search, MFM Communication Software, Inc.
		You may be searching for a word which appears on a page as a substring of a larger word, or a long word that has more than one form.
		If you are trying to search for a phrase that contains a comma, either precede the comma with a backslash character, or type a semicolon instead of the comma in your search string.
		"Fuzzy" searching is beneficial because it reduces the chance of missing a web page due to incorrect spelling of a word or phrase, or the use of acronyms on a web page.

	String searching algorithm Summary
		String searching algorithms, sometimes called string matching algorithms, are an important class of string algorithms that try to find a place where one or several strings (also called patterns) are found within a larger string or text.
		Baeza-Yates and Gonnet uses bits in a word to keep track of whether the previous j characters were a prefix of the search string, and is therefore adaptable to fuzzy string searching.
		Some search methods, for instance trigram search, are intended to find a "closeness" score between the search string and the text rather than a "match/non-match".

	Fuzzy string searching - Wikipedia, the free encyclopedia
		Fuzzy string searching is the name for a category of techniques for finding strings that approximately match some given pattern string.
		Sellers' algorithm searches approximately for a substring in a text while the algorithm of Wagner and Fisher calculates Levenshtein distance, being appropriate for dictionary fuzzy search only.
		Bitap algorithm is the heart of Unix searching utility agrep.

	Re: Fuzzy string searching. String distance algorithm based on a tree technique?
		Light bits in one string corresponding to nodes that are connected in one tree and bits in the other so they correspond to nodes connected in the other tree.
		The Hamming distance between the bit strings is the distance between the 2 trees.
		A fuzzy search can be computed by specifying the maximum Hamming distance that can separate similar strings.

		Fuzzy search databases can be amassed that compile common misspellings (or variants) of specific words which can then be substituted during the cleansing process.
		The output of a Fuzzy Lookup transformation includes those pass-through fields that the developer requires for downstream data-flow operations, as well as additional metrics that provide metadata around the fuzzy searching operation that was conducted.
		When configuring a Fuzzy Lookup in an SSIS data flow, there are several key decisions to be made regarding match index reuse, reference table sources, similarity thresholds, and the input and output columns that determine a record's uniqueness.

	fuzzy logic - Hutchinson encyclopedia article about fuzzy logic
		The term ‘fuzzy logic’ was coined in 1965 by Iranian computer scientist Lofti Zadeh of the University of California at Berkeley, although the core concepts go back to the work of Polish mathematician Jan Lukasiewicz in the 1920s.
		For example, a vacuum cleaner launched in 1992 by Matsushita uses fuzzy logic to adjust its sucking power in response to messages from its sensors about the type of dirt on the floor, its distribution, and its depth.
		Fuzzy logic enables computerized devices to reason more like humans, responding effectively to complex messages from their control panels and sensors.

	Apache Lucene - Query Parser Syntax
		If you are programmatically generating a query string and then parsing it with the query parser then you should seriously consider building your queries directly with the query API.
		For example to search for a term similar in spelling to "roam" use the fuzzy search:
		To boost a term use the caret, "^", symbol with a boost factor (a number) at the end of the term you are searching.

	Reasons for Movie Ratings (CARA) - Guide to Searching for Movie Ratings
		If you want to limit your search to a specific rating, change the default ANY to the rating of your choice: G, PG, PG-13, R, or NC-17.
		From within IMDb, remove the year from the end of the title string and search again using their "fuzzy" search.
		If you click on a title and the IMDb returns a Title Search Failure, try entering the title without the year in the IMDb Fuzzy search input field.

	Fuzzy searching at NAL
		One of the difficulties in searching any data resource is the lack of a facility to find items that are close to, but not exactly like, the search term(s) of interest.
		Other common usages include searching for a person's name for which you are unsure of the spelling, and to accommodate slight differences in gene nomenclature among taxa.
		Search terms can be combined to perform boolean searches using a terse notation: "this,that" translates to "this or that"; "here;there" translates to "here and there".

	Intervals on Maps - rearranged/translocated regions/QTLs
		Just like a WAIS search, a fuzzy search is performed against an entire database or set of databases, not just a single class, so it is also appropriate when you're not sure which class might contain the information.
		The ability to use wildcards (remember it's the #) anywhere in the search string and the fact that all the records meeting the criteria are returned are the main advantages of the fuzzy search over a WAIS search.
		Fuzzy searching may take longer however, particularly if you are searching many databases and are allowing mismatches.

		String data can be restricted to an encoding of Unicode or the default charset of the locale for the terminal window.
		If the string is limited to a specific byte length, special processing might be necessary to ensure that only entire character values of multibyte characters are read into the string buffer.
		Searching is conducted by the API on the normalized and in some cases canonicalized strings.

	Searching for Words and Phrases
		Also, you may want to search for the word "editor" and not the word along with all of its stemmed variations.
		This modifier affects how documents are scored and tells the search engine to give the highest scores to documents with the highest density of word matches.
		Document scores are calculated based on the relative number of words between search terms; the closer the search terms, the higher the score.

	Approximate/fuzzy string search in PHP
		This PHP class, approximate-search.phps, provides non-exact text search (often called fuzzy search or approximate matching).
		The code is optimized for repeated searching of the same string, e.g.
		We search the full text for these parts first and discard immediately those portions of the text that don't contain at least 2 of the patterns sufficiently near each other and in the correct order.

		This means "search globally for matches to the regular expression re, and print lines where they are found".
		Many text- and word processors now employ regular expression search features, which those applications will often refer to as a "grep tool" or "grep mode" in which one creates "grep patterns", hence the confusion, especially in non-Unix environments.

	Girill and Luk
		For example, the fuzzy signatures (bit strings) for `vectorization' and for `Fourier transform' should allow them to be properly distinguished, but the signatures for `vectorization' and for `vekterisation' should allow their dominant syntactic similarities to yield an approximate match that would otherwise be missed.
		Although a hash function is used to generate the signatures that enable fuzzy matching, the comparison of a search-term signature with database-descriptor signatures cannot be accelerated by using a hash table.
		Interpreting the results of a fuzzy search can be confusing, especially for those unfamiliar with how the approximation(s) to their search term were built.

	Glossary of Internet & Web Jargon
		Searching is usually more efficient, but sometimes you find things by browsing that you might not find because you might not think of the "right" term to search by.
		Search, and some other search engines, there is usually a Cached link which allows you to view the version of a page that the search engine has stored in its database.
		Most use "fuzzy and" combined with factors such as how often your terms occur in documents, whether they occur together as a phrase, and whether they are in title or how near the top of the text.

		String theory, and more precisely superstring theory, describes the assortment of elementary particles such as quarks and leptons, and the gauge bosons responsible for mediating forces in a unified manner as different modes of vibration of a single extended string.
		It is no longer a fuzzy probability but must be the opposite of the other particle, so that their spins will add to zero.
		The extra "hidden or small dimensions in the string theory are described as infinitesimally small or curled up so that they are not visible (to us in our 3D and time reality, at least).
