A Fuzzy search is a process that finds web page matches that are likely to be relevant to the search argument even when words are only partially spelled or misspelled. A fuzzy search searches for all source terms that are similar and identical to the search text. This type of search is done by means of a fuzzy matching program, which returns a list of results based on likely relevance even though search argument words and spellings may not exactly match. Exact and highly relevant matches appear near the top of the list. Subjective relevance ratings, usually as percentages, may be given to determine the results’ relevancy..
Fuzzy searching is especially useful when searching for unfamiliar topics, foreign language terms, or complex terms, the proper spellings of which are not widely known. Fuzzy searching can also be used to locate individuals based on incomplete or partially inaccurate identifying information.
