Lucene supports finding words are a within a specific distance away. The default that is used if the parameter is not given is 0.5. The value is between 0 and 1, with a value closer to 1 only terms with a higher similarity will be matched. Starting with Lucene 1.9 an additional (optional) parameter can specify the required similarity. This search will find terms like foam and roams. For example to search for a term similar in spelling to 'roam' use the fuzzy search: roam~ To do a fuzzy search use the tilde, '~', symbol at the end of a Single word Term. Lucene supports fuzzy searches based on the Levenshtein Distance, or Edit Distance algorithm. Note: You cannot use a * or ? symbol as the first character of a search. You can also use the wildcard searches in the middle of a term. For example, to search for test, tests or tester, you can use the search: test* Multiple character wildcard searches looks for 0 or more characters. For example, to search for 'text' or 'test' you can use the search: te?t The single character wildcard search looks for terms that match that with the single character replaced. To perform a multiple character wildcard search use the '*' symbol. To perform a single character wildcard search use the '?' symbol. Lucene supports single and multiple character wildcard searches within single terms Lucene supports modifying query terms to provide a wide range of searching options.
