### Intercanvia els caràcters

### Suprimeix caràcters

Enter the number of characters by which a word can be shorter than the search term.For example, if you specify 3 removed characters, "longitude" and "longest" are considered similar, but not "long".

### Combina

Cerca un terme que coincideixi amb qualsevol combinació de configuració de cerca per similitud.

Using Combine better meets a user's expectations from looking at the settings, but may return false positives. Not using Combine may match less than expected, but does not return false positives.

A Weighted Levenshtein Distance (WLD) algorithm is used. If Combine is not checked, then settings are treated as an exclusive-OR (strict WLD). If Combine is checked, then settings are treated as an inclusive-OR (relaxed WLD).

Be careful when using Replace All with Similarity Search. Best to be certain first about what will be found.
