Levenshtein-based search

The levenshtein attribute maintains an index of keywords across other attributes which can be searched using the levenshtein algorithm.

There is a filter rule that enables a similarity search via the created index. Optionally, an auto-completion ("Vanilla Script") can be activated (please note the template selection).

Adjustment of the index table

The fields for storing the index can be enlarged as required e.g. from a length of 64 to 256. To do this, create a corresponding DCA file and adjust the values. (Note: the keys and the file name still have the old, wrong notation with "sth").

// contao/dca/tl_metamodel_levensthein_index.php
$GLOBALS['TL_DCA']['tl_metamodel_levensthein_index']['fields']['transliterated']['sql'] =
    'varbinary(256) NOT NULL default \'\'';
$GLOBALS['TL_DCA']['tl_metamodel_levensthein_index']['fields']['word']['sql']           =
    'varchar(256) COLLATE utf8_bin NOT NULL default \'\'';
