Looks for best match of a text in a list of texts.
If not found, returns empty result, so FileMaker function isEmpty() will tell you if it's empty (instead of just having no text).
Uses internally the Text.LevenshteinDistance function to compare all items and look for best match.
If no entry matches over 50%, this may return empty text.

See also QuickList.BestMatch in case you need to query several times and want to load list only once.

MBS( "List.BestMatch"; "Test¶Hello¶World¶Hallo"; "Hilo" )
