DataTables example Fuzzy Searching

Fuzzy searching is used in search engines and databases to perform searches that will match results that are not necessarily exactly the same as the search term. This allows spelling mistakes and typos to be accounted for. It also allows small changes in dialect not to affect search results. A commonly used example is for surname searching. "Smith" and "Smythe" are pronounced the same way, but using conventional searching typing "Smith" would not return "Smythe".

This plug-in adds fuzzy search functionality to DataTables. It does this through a combination of exact matching and the Damerau-Levenshtein algorithm. There are three initialisation options that are associated with this plugin.

  • fuzzySearch.toggleSmart allows the searching to be changed from exact matching to fuzzy searching.
  • fuzzySearch.rankColumn allows the % match to be set in a column within the Datatable. Some examples of use cases could be to display the value to the user. or to hide the column and order based on it - as a search engine would.
  • fuzzySearch.threshold allows the value of similarity that is required from the Damerau-Levenshtein function to display the row to be changed.

This example shows how fuzzySearch integrates with stateSave. The search mode, the value within the search box and the search results are restored as they were on reload. To display all of the stateSave functionality, fuzzySearch.toggleSmart and fuzzySearch.rankColumn are set to true and 6 respectively.
