fuzziness in augmented search

Question

How does fuzzines in Augmented Search work?

Answer

In Augmented Search, fuzziness is enabled if the search string is longer than 4 characters. In which case, we apply a fuzziness of one. Spaces are counted for fuzziness, but they are trimmed.
Fuzziness is not customizable.

For a given string, fuzziness will keep the first 2 characters as prefix for the transpositions/expansions, so if we search 'TR', for example, it will only find words starting with TR, so it this case it will be exact matches and won’t find results with SR or BR etc.
