|Enter fuzzy search mode. Most of you probably haven't noticed the little number box next to the Named field in xplorer² search and other similar dialogs (see the picture). This can be used for approximate (fuzzy) searches. The default value of 100 means "find what I tell you 100% exact", that is a literal search of what you type for a Name. Lowering the percent accuracy resembles a "sounds like" search mode; the smallest the number the greater the fuzziness.|
Arguably fuzzy search is not very useful except when it comes to accented vowels. Setting the number to 99 turns on the accent insensitive matching mode that means all accents are dropped and vowels are converted to their simplest form, e.g. all ö ô o etc are equivalent, and so searching for rôle will match both its accented and normal role variations. So finding non-english filenames becomes much easier.
Accents also complicate searching for text within files, not just filenames. There is no way to tell xplorer² to use fuzzy search for file contents but one of the advantages of ultimate version is that windows indexes contents without regard to accents, and so you can search for accent-insensitive keywords too!
