→Fuzzy Querying
==Fuzzy Querying==
In addition to the official recommendation, BaseX supports a fuzzy search feature. The XQFT grammar was enhanced by the FTMatchOption <code>using fuzzy </code> match option to allow for approximate results in full texts. Fuzzy search is also supported by the full-text index.:
'''Document 'doc.xml'''':
Fuzzy search is based on the Levenshtein distance. The maximum number of allowed errors is calculated by dividing the token length of a specified query term by 4, preserving a minimum of 1 errors. A static error distance can be set by adjusting the <code>[[Options#LSERROR|LSERROR]]</code> property (default: <code>SET LSERROR 0</code>). The query above yields two results as there is no error between the query term “house” and the text node “house”, and one error between “house” and “hous”.
Fuzzy search is also supported by the full-text index.
