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 demonstrates the use of the fuzzySearch.toggleSmart initialisation option. The default value for this option is undefined which leads
to fuzzy searching being used all the time if the fuzzySearch option is declared in the initialisation options. In this example fuzzySearch.toggleSmart
is set to true, meaning that the search mode can be toggled by the end user. This can be done by hovering over the search box. When doing so a tooltip
will appear with two buttons - one for exact searching and one for fuzzy searching. Alternatively the fuzzy searching logo can be pressed. This logo is blurred when
in fuzzy search mode, and clear when in exact search mode. fuzzySearch.rankColumn is also set to 6 to display how the similarity is shown
when toggling between exact and fuzzy searching modes. When exact searching no value is shown here.
