Search: Fuzzy Search (Proximity)

You can search for terms that are similar but a bit "fuzzy". Therefore you can use the "fuzzy” operator which is a Tilde following your search term in the advanced search.

The fuzzy search uses the Damerau-Levenshtein distance to find all terms with a maximum of two changes. Changes are added, removed, or replaced single characters. The default is 2, but you can change this by adding a number to the Tilde and change it to 1, which should work for 80% of cases.
