Fuzzy string searching is the name for a category of techniques for finding one or more substrings of a text that approximately match some given pattern string. The bitap algorithm is one fuzzy string searching algorithm that is efficient for relatively short pattern strings. The bitap algorithm computes the levenshtein distance between two strings assuming it is smaller than a small integer n. ...

Soundex is a phonetic algorithm, an algorithm for indexing names by their sound when pronounced in English. ... In computing terms, a spelling checker (also spell checker) is a software program designed to verify the spelling of words in a file, helping a user ensure his/her spelling is correct. ... String searching 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. ... The term wildcard character has the following meanings: Telecommunication In telecommunications, a wildcard character is a character that may be substituted for any of a defined subset of all possible characters. ...
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 searchstring.
"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.
Stringsearching 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 searchstring, and is therefore adaptable to fuzzystringsearching.
Some search methods, for instance trigram search, are intended to find a "closeness" score between the searchstring and the text rather than a "match/non-match".
